It's from a restaurant called Doughboys. From the menu at www.doughboys.net:

the monster: it's big, it's gooey, it's messy, it's great. a big round of grilled focaccia (looks like a fat tortilla), topped with melted emmanthal cheese, grilled onions, mushrooms, and roast beef. served hot, and open faced, (it looks like a pizza but you eat it like a big taco) it comes with some shredded lettuce, diced tomato, and horseradish sauce
