Puzzled Pint!
Details
Hey all! You should check out Puzzled Pint! They do a fun event once a month where you show up at a bar, have a beer, eat some food, and solve some fiendishly hard puzzles. For more info, visit their website at:
http://www.puzzledpint.com/
They'll post up a puzzle with the location to the event on the Friday beforehand.
They recommend groups of up to 3-6. You're welcome to come and say hi and pair off into your own groups. We'll also try to help people find groups if they show up by themselves.
