Yes, the one on Old Georgetown Road. Maybe I'm wrong about there being a DC one as well. I thought there was a store near Dupont Circle with the same name, but it may just be a similar one, or I may be completely out to lunch. (The most likely alternative.)
My visit to Bethesda a year ago was a bit depressing. It's always been fun to get up there for an hour or two when I visit DC. On a sunny afternoon it was exhilarating to walk around this lively area with all the used and specialty bookstores and restaurants with sidewalk cafes. But last time I went, several of my favorite stores were gone, after many years of reassuring permanence.
