Mini-Burgers (aka sliders): Matchbox
Yeah, Matchbox is a pizza place. But the mini-burgers here are so popular that they helped put this mini-chain on the map. They can be ordered in batches of three, six or nine; each comes with a carefully placed pickle slice; and the whole thing is stacked high with onion straws. If you decide to go at the last minute during prime time, you can call ahead and put your name on the waiting list before you head out of the house or office.
