We are heading to **Elmina** in Shaw, from Top Chef finalist and Food Network personality Eric Adjepong, known for bringing modern Ghanaian cuisine into a refined dining setting. **FOOD**: Elmina blends traditional West African flavors with modern technique, with a menu that highlights depth, spice, and layered composition. Dishes frequently called out include the jollof duck pot and egusi stew dumplings, both reworking classic Ghanaian staples into more refined presentations. You will also find grilled meats with suya-style seasoning, seafood dishes with balanced heat and acidity, and rotating plates that reflect regional influences. The menu leans bold and savory, with options across meat, seafood, and some vegetarian-friendly selections. Cocktails often incorporate tropical and spice-forward elements that align closely with the cuisine. Most members should expect total spend to land roughly in the 55 to 85 dollar range, depending on beverage participation. → **Explore Elmina's menu:** **[https://www.elminarestaurant.com/menu](https://www.elminarestaurant.com/menu)** **SPACE**: Stylish, modern dining room with a warm, intimate layout.

If you don't have any drums, there may be extra available. Either way, you can chant along with everyone. Seating is limited so we recommend bringing a chair or blanket to sit on. In the event of inclement weather, we usually drum as long as we can before the storm starts, or wait it out and start a little late.

Many other regions of the world are also experiencing drought conditions. We will dedicate our prayers to bringing life-giving rain to all who need it!

This class is a perfect stepping stone from our flagship My Body Don't Bend That Way classes to traditional Vinyasa and Flow classes.

Capoeira (capo-way-ra) is an Afro-Brazilian martial art that is unlike any other martial art. Capoeira incorporates flowing movements with kicks, dodges, and some acrobatics. It is often mistaken for a dance for those reasons. Since it’s origins in the 17th century, it has evolved from a secret fighting practice into an art emphasizing self-expression and community celebration. It is great for the body and mind! In addition to gaining strength and flexibility in class, students learn about Brazilian culture, history, and language (Portuguese). On November 26, 2014 capoeira was granted a special protected status as "intangible cultural heritage” by UNESCO. No need to have a Capoeira background to join this class, just an open mind to try out a new way to move! Beginners welcome. **Please reserve your spot at www.piesfitnessyoga.com**.

**History** The [Franklin Park Conservatory](https://www.fpconservatory.org/)’s roots trace back to 1852 when the Franklin County Agricultural Society purchased 88 acres of land to host the Ohio State Fair. After the fair moved to its permanent home, the city of Columbus transformed the grounds into Franklin Park in 1884. This transition shifted the space from a temporary event site to a dedicated public green space for the growing community. The park became a central hub for outdoor recreation and early civic gatherings in the neighborhood. In 1895, the landmark Victorian-style Palm House opened its doors, drawing heavy inspiration from the Glass Palace of the 1893 World’s Columbian Exposition in Chicago. This iron and glass structure became an immediate icon, housing exotic plants that residents would otherwise never see in the Midwest. It remains the oldest part of the facility and serves as a primary link to the conservatory’s 19th-century origins. For decades, it stood as a singular testament to grand horticultural architecture in Central Ohio. A major turning point arrived in 1992 when Columbus hosted AmeriFlora '92, an international horticultural exhibition. This massive event prompted a $16 million renovation and expansion, adding significantly more greenhouse space and the Dorothy M. Davis Showhouse. The festival put the conservatory on the international map and fundamentally changed its scale and ambition. Following the event, the facility transitioned from a city-run park to a private, non-profit organization. In 2003, the conservatory’s identity was further defined through a long-term partnership with world-renowned glass artist Dale Chihuly. After a successful exhibition, the Friends of the Conservatory purchased most of the glass installations, creating the largest permanent collection of Chihuly’s work in a botanical setting. These vibrant glass sculptures are now woven throughout the biomes, blending art with nature. This addition helped cement the conservatory as a premier cultural destination rather than just a botanical garden. Recent years have seen the site expand beyond the glass walls to emphasize community engagement and outdoor education. The 2018 opening of the Scotts Miracle-Gro Foundation Children’s Garden added two acres of interactive landscape designed for hands-on learning. The Scotts Miracle-Gro Company Community Garden Campus also provides local residents with space to grow their own food and learn sustainable practices. Today, the conservatory balances its historic Victorian charm with modern commitments to local ecology and the Columbus community. **Maps of the Conservatory** Here is the [main map](https://www.fpconservatory.org/wp-content/uploads/2025/08/franklin-park-zones-scaled.jpg) of the Conservatory grounds. Here's a [map of the areas](https://www.fpconservatory.org/wp-content/uploads/2026/02/ConstructionMap-2026.jpg) in which the Conservatory has ongoing construction (see below). **Summary** For this event, we'll explore Columbus's highly-rated and very popular Conservatory. As mentioned above, the Conservatory is doing renovations on parts of the facility. These renovations are scheduled to be ongoing until the Fall of next year. Basically, no matter when you go to the Conservatory over the next 18 months, you're going to see some metaphorical orange barrels. So let's just go now. **Tickets and pricing** On the first Sunday of every month, the Conservatory is free for residents of Franklin County and the city of Columbus. You must bring an ID to receive this discount. (Yes, they do check.) Otherwise, tickets are $25.20. Members of the Columbus Zoo (of which I am one) do get a discount on tickets, though I have never actually bought a ticket to the Conservatory (I've always gone on free days). I believe the discount is $4. Parking is always free. If you have additional questions about pricing or whether and for what you qualify, you can reach the Conservatory at 614-715-8000. **Where we'll meet** We will meet just outside the main entrance. I guarantee there's going to be a line. The Conservatory is always popular on free days, and especially in nice weather. **Your GPS is stupid!** Be careful simply typing "Franklin Park Conservatory" in your GPS and going where it tells you. The only way to access the parking lot to the Conservatory is off of Broad Street. Unfortunately, since Google Maps is unable to find its way out of a wet paper bag, it has a tendency to want to take people to a mythical, non-existent Conservatory entrance on Nelson Road. If your GPS does this, just drive to the north side of the Conservatory along Broad Street. Your GPS should then redirect you to the main Conservatory entrance. If your GPS doesn't, then throw your phone away\* and look for the big Conservatory sign on the south side of Broad Street between Nelson Road and Franklin Park West. You also should be able to use the map pin I've provided, below, and it should properly direct you to where you need to drive. \* Don't really do this. **After the event** After stopping to smell the roses, for those that are interested, we'll head to the nearby [Columbus Brewing Company Beer Hall](https://columbusbrewing.com/location/beer-hall/) for [drinks](https://columbusbrewing.com/location/beer-hall/#draft-list) and [lunch](https://columbusbrewing.com/location/beer-hall/#food-menu). The Beer Hall's actual address is [200 Kelton Ave, Columbus, OH 43205](https://www.google.com/maps/place/200+Kelton+Ave,+Columbus,+OH+43205/data=!4m2!3m1!1s0x883889a94ac4acad:0xadb2e60240dbc38b?sa=X&ved=1t:242&ictx=111) (it's literally just on the south side of the Conservatory). Be sure this is where your GPS is taking you when you use it, as the Brewing Company has a taproom on Harrison Avenue that is *not* what you want for this event. We should be at the Beer Hall by 1 if you can't make the Conservatory and just want to join us for drinks.
