My fiance and I are starting to plan a pretty informal wedding for next summer, and are trying to think of a great Brooklyn spot to use for a reception. We are thinking about getting married in Prospect Park, and then taking everybody (maybe 50 people) somewhere nearby. Any suggestions for a place near the waterfront / park slope / boerum hill etc.? River Cafe is obvious but out, as our budget is modest. It would have to be a place that serves liquor and some food (but not necessarily a sit-down dinner,) and of course be open to the idea of us renting it for the afternoon. Good food a must. Your thoughts would be appreciated.
