I'll take note of where you're meeting on Thursday evening, Frank, but it's not likely I'll make it. If I can, I'll just show up.
From going to a few flickr meets, two names I'll throw out for now: the Cadillac Lounge, & the Bedford Academy. Both of these have good patios, but are in Parkdale and the Annex, respectively. Jack and Jan may be able to comment on Betty's. I don't know if the Madison has a patio; been there, but at night for indoor ski club meetings. It's a huge place.
Jan, is Hair of the Dog high end? The (lukewarm) on-line reviews seemed to suggest that. E&C is ok; I don't know that location.
I would guess we'd like a patio, though the forecast isn't for summery weather. Dry, but temps in the upper teens.
