Though the restaurant itself is kinda tiny, Nic's Grill serves up some massive, juicy 1/2-pound burgers that get people lining up around the block. Don't let the wait deter you—biting into one of those moist-on-the-inside-yet-crispy-on-the-outside hand-packed patties is totally worth it. Irish actor Collin Farrell even said it's the best burger he's ever eaten on Jimmy Kimmel Live. Just be sure to bring cash, as they don't take cards.
