Can't think of any 'must-see' shops anywhere. But, if you're downtown near the White House, Drapers is worth a look. Nice selection, good staff and one of the higher profile shops in the region. If your brother and wife don't mind the atmosphere, Shelleys (around the corner from Drapers) has decent food and you can smoke your own there. Plenty of other decent shops around. Depends mostly on where you are and whether you want to travel to one of them. Navigating around here is often bad enough to dissuade you from traveling just a few miles for something.
