Before my sister left Japan, we took her to Nabezo for a delicious fulfilling meal before heading home (and unlikely to get these kinds of food for a long time). Nabezo is an all you can eat hotpot restaurant, and not only it's delicious, it's also a ridiculously good deal - can't beat that combo, can we? I really recommend this place if you have a big party you would like to feed without breaking anyone's bank. You can bet that everyone will leave the place satisfied and stuffed silly.
Our mix hotpot with Sukiyaki (right) and Soy Milk Collagen broth (left), they literally gave us a bowl of collagen to mix in with the soy milk! It was a harmoniously delicious mix (corny, I know) :P
