I live in NYC and I'm planning two dinners in March--both restaurants must be in walking distance of Harvard Square:
1. should be more informal, for about 10-15 people. Good Thai, Middle Eastern, etc.
2. for 25-30, I talked to Daedalus--they have a room downstairs that we could have...but is the food decent? Also might try Casablanca.
Any other suggestions welcome.
