Whenever an established greasy spoon survives gentrification, I always celebrate! One of the greatest comfort foods in Japan is deep fried seafood and vegetables on a hot bowl of rice, drenched in a light sauce.
While beef bowls are nice, the freshly fried goodness of huge prawns with vegetables is delicious, so on your next visit consider the better alternative to the typical beef bowl you can easily find. This particular local favorite chain is far superior to other more modern chains, even better than Ginza and high street restaurants.
