When it comes to summer cookouts, the hot dog often gets overshadowed by the burger as a vehicle for creativity. But this Old Town cafe—lined with photos of terriers and retrievers—proves just how exciting a frank can be. Exhibit A: the Bombshell, done up with onions, mango-pineapple relish, and jalapeños. Still, the place does an admirable set of cheeseburger sliders, too. Also good: Bánh mì dog; Duck Duck dog; Chicago dog; lamb sausage; sweet-potato fries.
