Roti Mediterranean Grill is about 24 hours away from opening its new Rosslyn location.

The restaurant, at 1501 Wilson Boulevard, will open at some point tomorrow, according to a PR rep. The opening will be followed with a “free lunch day” on Tuesday, Jan. 17; customers who line up between 11:00 a.m. to 1:00 p.m. will be given a free lunch in exchange for a suggested donation to the charity Adoptions Together.

Roti, a Chicago-based chain, serves “healthy Mediterranean cuisine” in a fast casual environment.
