Firehouse, Hongou ファイヤーハウス本郷

The website says it's "Nippon's Tastiest Burger!!!". That's a pretty tall claim, but the mozzarella and mushroom burger I had the other was pretty damn good. These guys are at Hongou which is really close to Korakuen and Tokyo Dome.

Check 'em out! They also deliver if you live within 2.5 kms...
