Washington D.C. hosts a respectable amount of pun-inspired restaurants, especially in the Thai food domain. Thaiphoon, Mai Thai, TenPenh (located on 10th Street and Penn. Avenue), and Leo DiCaprio's favorite tom yum soup source, Thai Tanic.
But they have to compete against Thai Me Up, EnThaiSing and other non-Thai restaurants on the Best Week Ever's list of 50 Best Pun Stores. One of my favorites, The Grill from Ipanema, somehow didn't make the cut.
