Japan-based photographer Pete Leong took this great photo of his son Jet peering at the towering burger from Hiro, a coffee shop and restaurant by Lake Inawashiro. The burger is called the US Burger (note the American flag on top) and costs ¥880 (about $9). Leong says it's made of two huge burger patties, lots of lettuce, almost a full jar of mayonnaise, egg, cheese, onion, tomato, and ketchup between two freshly baked buns (the full jar of mayonnaise reminds me of mayo-packed Chilean hot dogs). He somehow managed to eat it all without exploding.
I'm not alarmed by the excessive patties and toppings as much as the disproportionate diameter of the buns compared to the fillings. That just ain't right. I'd totally try it though.
