I bought a class for myself and a friend who likes to cook for her bridal shower gift at L'Academie de Cuisine in Bethesda. (I think they have other locations as well.) They have all kinds of one-night classes--wine & food, cooking for two, and various cuisines.
The website is:

I'm not sure he still teaches but I liked Joel Olsen.
