Falafel and frites at Amsterdam Falafelshop

The fried-to-order falafel and frites are irresistibly crunchy at the Adams Morgan institution Amsterdam Falafelshop , but as reader Amber Wilkie of Arlington noted, "The allure of Amsterdam, without question, is the toppings bar -- a veritable wonderland of Middle Eastern relishes, pickles, spreads and condiments. It's impossible to fit everything into your pita, though it is possible to try and wind up very messy." (Various locations. 202-234-1969. www.falafelshop.com.)
