I had a look at the side events. btc/nostr events on Thu 13 / Fri 14 at bar no.7. Hack day Wed 12, but no after event. Duo is not a good place to hang out, but some may eat and other my smoke outside until sundown. People will scatter decentrally. Most convenient place would be again bar no.7 on the wednesday for an after event. There is outspill to, for example, the Groove bar. Wednesday should have plenthy of good places open though.
