I was on my way to my hotel from the city center early because of a bad head cold. I'm staying very…read morenear the train station where there are a LOT of Chinese, Vietnamese and Japanese restaurants. I decided to get a pho or wonton soup to soothe my throat and happened upon this place due to the jazz music coming a club across from Zen. It's kind of a 'Benihana' tepanyaki place if you are from the US. Anyway, they had Udon soup, so I decided to give it a try. Good soup. Noodles were not over cooked, a few shrimp, some 'Krab' strips, and a nice addition of crispy pork strips. Broth was just OK, didn't taste like some of the broths that have been stewing for hours and hours, but then why would it, since this place does not specialize in Udon. So if you are looking for a nice hearty soup because you are not feeling well, or just want something light, for 8 euros, I highly recommend Zen. Service is good and they speak English.
