Have a small group of out of town guests arriving at 1000 on Monday night (6 people). They'll be tired from a day of travel and I am looking for a nice place to walk to in Dupont Circle area that's open on Monday after 10. Looking for a good D.C. atmosphere since it's the first time they've been in the city for many years. Not looking for too ethnic (sushi, thai, ...). Thanks in advance.
