The Grilled Cheese Grill, Portland

Specialty: Twenty kinds of grilled cheese served inside a 1954 double-decker former Mount St. Helens tour bus that owner Matt Breslow outfitted with tables and painted on the sides to look like a big checkerboard. “It fits grilled cheese,” he says. “It makes you feel like a kid.”

Indulge nostalgia (or not): Sandwiches range from the crusts-cut-off Pre-schooler to the artery-clogging Cheesus, a burger sandwiched between two grilled cheeses. All offerings are in keeping with the company motto: “Come by for a taste of childhood. Unless your childhood sucked, and then we’ll let ya have a taste of ours.” grilledcheesegrill.com
