My boyfriend and I are looking for a midweek beach get-away this summer, and we want to go somewhere on the east coast with good casual non-chain restaurants. We're both vegetarian, so we don't live comfortably on boardwalk fare alone. We're from the DC area, and often go to Rehoboth Beach in Delaware - there are many good places to eat within blocks from the shore. I love it, but this year I'm looking for something different. We're willing to fly, so anywhere on the Atlantic is fine. Any ideas?
