My husband and I are heading out for an anniversary dinner on Sunday. Have a babysitter, so don't want to go too far (maybe 20-30 mins from Lexington), and don't want to go into Boston proper, but we'd like to go somewhere a little romantic where we can get a bit dressed up (not too fancy). I was thinking of trying J's at Nashoba Winery, but they're closed on Sundays. Flora in Arlington was a possibility, but they're just doing an extended Restaurant Week menu this month, which makes me cautious. Anywhere to recommend?
