In Episode 4 of Real World DC what looks like the all the houseguests (Andrew, Ashley, Callie, Emily, Erika, Josh, Mike and Ty) head out to dinner at Russia House Restaurant and Lounge located at the corner of Connecticut and Florida Avenues NW, Washington DC. I believe this is an early stop in a night of partying.
Interestingly outside the restaurant is a bronze sculpture of academician Andrei Sakharov by sculptor P. Shapiro.
The Russia House Restaurant and Lounge is located at 1800 Connecticut Avenue NW, Washington, DC. It is just across Connecticut Avenue from Buca Di Beppo, the restuarant the houseguests visited in Episode 1. Russia House is only about a block and a half from the Real World DC house.
