Trying to put together a last minute bridal shower for a friend for August 7th. Would love to have a private room for 10ppl for three hours on a Saturday afternoon w/out costing an arm and a leg. Thinking maybe $50 a head for food and drink. A tatami room would be great since one guest is strictly gluten-free and Japanese cuisine will help us mostly sidestep that. Any suggestions? Park Slope or Carrol Gardens are best for guest list... but obviously will travel for great place.
