They also serve some meals such as the prawn tempura udon. The prawn tempura is good, but unfortunately served in the soup where the crisp exterior is quickly lost. The noodles themselves and the dashi soup are nice and warming. It's very good for lunch on a cold day.
The main staff are Korean, not Japanese, and explains why they also serve bibimbap. It's quite an unauthentic version and only served with a tiny amount of gochujang sauce, so will avoid it next time.
