My husband and I tried Umami for the first time this week and were disappointed.  We started with shrimp and shitake mushroom dumplings, which were decent though they did not have a shrimp taste.  My husband had the veggie ramen and I had the pork version.  Both were overly salty; the veggie version had tastier broth but both were farily bland.  There were no subtle tastes.  Overall, the ramen bowls were passable but nothing we would return for.  The decor is soothing, clean and distinctive and the service was good.  The menu is limited but we did not try the appetizers or salads.
