I’ve been to Tsurutontan a few times already in various locations including Union Square and Midtown next to Rockafeller Center. When this Japan udon chain first opened in Manhattan a few years ago, there was a massive line because it was the first international location in the USA. The food was outstanding back then, and now it’s gone down a little in quality but still pretty good. This restaurant is known for having mammoth sized udon bowls which will most definitely satiate your appetite.
