Tasty Sushi Carousel Experience at Kura (Tysons)!
Join us for a fun experience with conveyor belt sushi and robots that serve drinks at **Kura Revolving Sushi Bar** (Tysons location)!
***NOTE: We'll be seated in 3 groups of 4 people. Each group will have their own tab - and should be able to split the bill using the ordering tablet. In the event that is not the case, please be prepared to calculate / split the tab with your table group (include 10% tax plus 20% tip). While some may be inclined to tip less due to the high tech nature of this experience, please be mindful that tips are shared between the restaurant and kitchen staff. Thanks in advance for your consideration.***
***Patch:***
Shoppers at Tysons Corner Center may be familiar with the revolving sushi bar on the lower level of the mall. Just minutes away from the mall, there's a standalone restaurant serving sushi and other Japenese dishes moved by a conveyor belt and drinks delivered by robots.
Kura Sushi is a Japanese restaurant concept established in Japan in 1977 and expanded to the U.S. in 2008. The restaurant brand helped establish the revolving sushi concept, which features sushi plates circulated around the restaurant by conveyor belt. There's also an express belt where kitchen staff can send dishes customers order by tablet at their table.
The menu features over 140 Japanese dishes free of artificial sweeteners, seasonings, preservatives and coloring.
One of the restaurant brand's technological features has been drink orders delivered by Kur-B the KuraBot robot. Staff typically receive orders, place beverages on the robots and program it to deliver to a specific table. Diners place orders directly on the tablet at their table and check out on their mobile phone.
The restaurant offers prizes once certain numbers of dishes are ordered. These prizes could include keychains, cable protectors and stickers. The prizes are usually available for purchase at the restaurant while supplies last.
Diners can also join the Kura Sushi Rewards program, which provides a $5 reward for every $50 spent, allows diners to see live wait times, join the waitlist remotely, and receive special promotions.
The restaurant brand has hundreds of locations in Japan, Taiwan and the U.S. The Tysons location is the 40th U.S. location and was the first in Virginia.

**WAITLIST:**
Meetup does not allow a waitlist for paid events. If this event fills and you are interested in adding your name to the waitlist, please send host a message through the app.
To enhance the opportunity for great conversation, we would like to keep the group small. Please feel free to sign-up to meet us along with up to 2 friends.
In the future, we will vary the days of the week, geography and the cost of restaurants so that we can attract many different types of diners.
PLEASE MAKE SURE YOU ARE COMMITTED TO GO WHEN YOU RSVP FOR THIS EVENT. In the event our group incurs a fee for no-shows / late cancellations, your ability to RSVP for future events will be restricted. Thank you in advance for your understanding.Feel free to make suggestions for future meet locations. All diners will have their own tab to avoid any confusion.
\*\* The small non-refundable registration fee helps us share the cost associated with Meetup platform ($360/year) and reduces the likelihood of no-shows, allowing us to better plan our events and accommodate attendees. Thank you in advance for your understanding!\*\*
If you are unable to join us in June, we hope you'll stay interested and join us for a meal in the future. Looking forward to seeing you at Kura in Tysons!

Read & Reflect: A Social Reading Circle.
Shared Pages, Shared Insights.
📚 Do you love reading, but wish you had a structure and a community to share your insights with?
Join our small circle of curious minds (just 4 members per gathering) as we come together for an hour of focused reading—in the calm setting of a library or the cozy atmosphere of a café.
Here’s how it works:
First part: Quiet reading on your own—bring a book you’re exploring, whether it’s philosophy, history, psychology, literature, or anything meaningful to you.
Second part: We regroup and each person shares key takeaways, insights, or questions sparked by their reading. This sparks a structured yet free-flowing conversation around ideas, perspectives, and personal reflections.
Why join?
Add structure to your reading habit.
Discover new books, authors, and ideas through others’ choices.
Build real connections by sharing and listening deeply.
Socialize around something meaningful instead of small talk.

We Built an AI Platform Using AI — Here's What We Learned
A small team of AWS Solutions Architects not traditional software engineers, built AIRE Traffic Control (ATC), a production agentic AI platform now serving thousands of builders. We used AI at every stage: spec-driven development, AI-generated code, automated testing, and agentic workflows. In this talk, we'll share the real story, the architecture, the failures, the breakthroughs, and what we learned about driving adoption from 32% to 92% in 10 weeks.
You'll walk away with practical patterns for building multi-agent systems, using AI-DLC methodology, and empowering non-traditional dev teams to ship production-grade applications.
Mid-Week Service
## **Mid-Week Service: Renew Your Spirit**
Join us every **Wednesday evening at 6:15 PM** for our Mid-Week Service, a dedicated time to pause, pray, and recharge in the middle of a busy week. Held in an intimate and welcoming setting, this service is designed to help you reconnect with God and find peace through His Word.
### **What to Expect**
* **Deep Biblical Teaching:** We move beyond the surface, engaging in verse-by-verse studies of Scripture—such as our current journey through the **Book of Acts**—to gain practical wisdom for daily life.
* **Community Prayer:** We believe in the power of collective intercession. Each week, we lift up the needs of our families, our city, and the world.
* **Heartfelt Worship:** A time of singing and reflection to center our hearts on the presence of the Holy Spirit.
* **Authentic Fellowship:** Connect with a supportive community of believers who are walking the same path of faith.
Whether you are looking for a deeper understanding of theology or simply a quiet place to sit at the feet of Jesus, our mid-week gathering offers the spiritual nourishment you need to finish your week with strength and purpose.

GeoDC : June 2026 Meetup
**The next GeoDC will be held on Wednesday, June 10 from 6-9pm at Sudhouse DC (1340 U St NW, Washington, DC 20009) with the program starting at 7pm.**
* Join us early from 6-7pm to grow your network, socialize and grab drinks and appetizers.
* Throughout the evening, we'll be sharing job announcements and details of other GIS/Geo upcoming events we're tracking.
* We look forward to seeing you on the 10th!
**Our Program will feature these presentations:**
**The Secret History of the Blue Dot - William H. Tewelow, GISP (GPS World)**
This presentation takes the audience from an iconic movie scene they recognize but never understood, through the hidden origins of GPS, and returns them to the blue dot in their own hand, seeing it for the very first time. There is a blue dot on your phone right now. It knows where you are to within a few feet. You have never questioned it. You have never wondered where it came from.
You should.
Its origins are classified. Its lineage runs through the Cold War, nuclear submarines, and a doctrine built on the promise of mutual annihilation. The technology that tells you where to turn was designed for something else entirely.
The technology did not change. Only the purpose did.
**GEOINT Symposium's Golden Ticket Program - Katie Weintraub (ESRI)**
This is a firsthand account of USGIF's GEOINT Symposium Golden Ticket — a program built for early-career professionals who want to level up their careers.
Participants get free admission to GEOINT Symposium, mentorship opportunities, a network of fellow Golden Ticket alumni, and a cohort of peers to grow alongside.
This talk breaks it all down fast — what it is and why it's a stellar experience for young professionals breaking into or already working in the geospatial intelligence realm.

Stop Guessing: A Product Person's Guide to AI Adoption
## 🤝 Host Information
A co-hosted event by ProductTank Columbus & Women in Product Columbus
💡 About the Workshop
AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge.
This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow.
Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required.
🛠️ What to Bring
Laptop: Fully charged and ready to go.
AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!)
🍕 Logistics & Perks
Food & Drink: Pizza and drinks provided!
Parking: Plenty of free spaces available on-site.

In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
