Good, solid American diner fare is the draw at Fatz's - tasty burgers, hearty sandwiches, tempting mozzarella sticks, milkshakes and banana splits. The menu lists eight burger variations with names like The Corleone (with zucchini, eggplant, bell peppers, mozzarella and meat sauce) and The Longhorn (topped with great home-made chili, Cheddar and Havarti). Or you can create your own custom burger with over a dozen optional toppings such as mushrooms, grilled vegetables, jalapenos and various cheeses.
While you're waiting for your burger to be grilled, the nachos con carne (Y600) are a great side dish - tortilla chips covered with two types of melted cheese, fresh salsa, guacamole, and some kick-ass chili. Non-beefy menu options include Pacific salmon burgers, shrimp-avocado sandwiches, and a grilled chicken of the day sandwich, prepared with an ever-changing list of pre-grill marinades.
At lunchtime there's a smaller menu - just plain burger platters with cole slaw, fries and a beverage for Y850; optional cheese, bacon and avocado toppings are Y100 each. There's also a nice beer selection, with US microbrews from Brooklyn Brewery, Kona Brewing and Anchor. And for just Y500 a bottle, four very drinkable Kirkland-brand microbrews - amber ale, pale ale, IPA and Belgian white.
In addition to counter seating there's one picnic table out front in the courtyard. Everything on the menu is available to take out.
