Tried this place with my boyfriend tonight and was very impressed. I will be honest I am not a ramen expert but we were both very happy with our meals as well as the service. I had the Paitan preparation with roast pork and the boyfriend had the miso with the chicken. The presentation was beautiful with the nori, carrot "flowers" and fish cake. The roasted garlic and corn extras were really tasty. Other reviews comment that the ramen is pricey, but my opinion is dinner out for two for about $20 isn't too bad, especially if it tastes good.
I also want to add that this is a stark contrast to the "Ramen night" at Posh. I thought the flavors, presentation and service were much better at Umami than at Posh, and Umami is much less expensive than Posh too.
I can't wait to bring more friends here!
