My boyfriend's brother, who lives in NYC, is coming into town this weekend to catch an exhibit at the Portrait Gallery. He's passionate about a good steak and - having lived previously in Chicago - has arguably been around and in some of the better steakhouses. We're trying to figure out a place to go in DC that doesn't necessarily need to "wow" but will leave him happily sated. Is BLT Steak here any good? Other ideas for a sublime steak dinner?
