BuiltBurger began (and continues) as a mail-order meat service; the Pioneer Square location is the first brick-and-mortar restaurant to serve cooked versions of the patties to the public. It’s counter service in a minimalist space that’s faintly reminiscent of the area’s many art galleries, putting pressure on the burgers to provide a certain level of meaning. And they do: Not only are the ingredients a good medium (including locally sourced beef and organic toppings and buns), but in a feat of formalism, BuiltBurger puts the toppings inside the patties themselves. Try the Magnificent Chorizo: ground beef with Mexican sausage, poblano peppers, and cotija cheese. It is a great, spicy treat—not too greasy, with a perfect amount of fiery kick.
