One of the best burgers I have had in a while is at Bareburger in the new Tokyu Plaza in Ginza. The organic burger is made from Aussie beef. It’s a meaty and hearty burger. I had the Standard (1,380 JPY) and Shinji had the Buck Wild with a fried egg and fried onions (1,640 JPY). We shared a large serving of onion rings and fries (1,050 JPY), sold as side dishes. The prices seemed fair for organic ingredients and for the great location and ambience. Staff are friendly and genki. I drink a lot of water with my meals and the staff were great to keep my water cup filled. This often goes ignored at other restaurants. Arigato.
The first Bareburger shop is in Jiyugaoka, but that is a neighborhood I just never get to. The Ginza location, just near the Sukiyabashi crossing, close to Ginza and Yurakucho stations, is very convenient. This is on the 10th floor and has lovely window-side seats that overlook Ginza. The shop is also kid-friendly. Bareburger is an import from NYC to Tokyo.

Food Sake Tokyo 
Agreed. The best burger in Tokyo. And proper French fries – not wedgies or crinkle cut “fries” at that other recent, greasy, American import.
