My parents and my sisters (both teens) will be visiting me in D.C. during Mother's Day weekend. I'm looking for recommendations for restaurants that offer good, reasonably priced food and are nice without being upscale. (It'd also be great if they take reservations, as I'm sure that'll be a busy dining weekend!)
I've seen the Talk threads on some of the best D.C. restaurants, and I've even offered up recommendations myself, but it'd be great to learn of a few places that aren't necessarily trendy/of-the-moment. Thanks!
