If you fancy a FANCY New York style burger, and don't mind a little walk from Kagurazaka station, then this is your spot - Martini Burger.
The food is delicious and novel, with about a dozen themed burger recipes to choose from with flexibility for custom toppings.
I had a delicious "Little Italy" burger with mozzarella cheese, basil sauce, and eye-wateringly spicy ketchup. That was paired nicely with a non-alcoholic chocolate soda.
It features spacious seating with a sleek modern decor, and a nice sound system make for a great environment. The all glass wall along the entrance lets in a ton of light and makes it feel even bigger.
Price is on the high end for a burger joint, but I wasn't upset at paying ¥2000 for my burger/drink combo. Seems great for an upscale yet fun and casual date.
