Geez, if I were you, I wouldn't eat at a chain restaurant while vacationing. (I wouldn't eat at a museum either.) Try something new! I don't have names of places because my in-laws who live in DC always pick the restaurants, but there are plenty of decent non-chain restaurants that aren't too pricey. I suggest you try www.yelp.com. Search on restaurants in DC and you'll see a ton of reviews of different places. Good luck - enjoy your trip.
