Amer's sounds good to me. I'm not aware of any good space in Hatcher Grad Library where meeting and talking would be easy and comfortable, but I don't know the whole story, so maybe there is one. Shapiro Undergraduate has Bert's Cafe and some nearby areas that might be workable, but I'd still prefer Amer's.

Bound_up, please set up a poll soon, or make a unilateral decision kinda-soon, so that the place is settled a good while before the actual event.
