Looking for a restaurant to take a total of seven people to celebrate my daughter's graduation from Vassar College. Here's the catch: Commencement is on Sunday, May 28 in the morning (Memorial Day weekend) and I'm having trouble finding a restaurant (that's not a chain) open on a Sunday afternoon. We'll travel up to around 15 miles, including to the other side of the river. We're adventurous eaters, and it doesn't need to even be anything fancy. Any suggestions?
