I belong to a Stitch n Bitch that meets every Tues. night and we've been having real problems finding a new spot. The most recent two - Dean & Deluca on Univ. Pl. and The Tea Spot on MacDougal - both had climate control issues which is a real problem during the second hottest summer on record and when you're working with wool.
Here are our needs: Good lighting, reasonable selection of inexpensive food, enough seating for up to 25 people (although that many is rare, 15 is probably more standard), close to subways and decent a/c.
