I absolutely love this place.
Let me start off and say that my husband has spent a lot of time in Japan (and had his fair share of Japanese Ramen dishes), and he also absolutely loves this place. The flavor of the Miso is very authentic (with the added bonus of the pork!) The pork buns are also amazing (small and pricey, but worth it for sure). I haven't tried any other of their dishes (other than another ramen dish that was a special of the day), so I cannot comment on those, but I have heard good things about them.
There can be a wait (sign of good food!) at times, but if you go early enough, you should beat the crowd. Street parking is the best, and cheapest option, if you don't live nearby. (there is no parking lot for it)
The portions are large (in my opinion), and make for great leftovers! It is a little bit $, but it is definitely worth it!
