Smashburger, and order-and-seat-yourself eatery, has a great concept. Take Five Guys, add chicken and veggie patties as options, and update the toppings and sauces to include the coveted avocado and a spicy chipotle mayo (which was delicious once I convinced myself to forget how gross mayonaisse is).
A variety of sides includes something for everyone, like fried pickles, salads, and the "smashfries" in regular and sweet potato varietals. Topped with rosemary and salt, these greasy bad boys won the prize for the night. The black-bean patty was quite tasty and the multigrain bun wasn't too dry.
I'd probably return for another visit, but not unless I were already in the area.
