Stopped by the new Amsterdam Falafel Shop in Adams Morgan yesterday, and it seemed like they had just opened.
They have a huge bar you can dress your falafel from, with sauerkraut, pickles, pickled beets, pickled vegetables, yogurt & cucumber sauce, olives, hummus, 2 kinds of tahini, and about 10 other items. They also serve special "stuffed falafel" which I didn't try, and fries. My falafel was great loaded up. We really needed a place like this in DC.
