I always have very good to excellent sushi & very good miso soup here. The place was a great find in an otherwise not impressive area. The restaurant staff have been very attentive to my orders, & pack the food extremely well. Portions are good. The menu has a good variety of options for even non-sushi lovers.
I haven't heard anyone else say anything but great things about Umami.
*Update* Today - another great meal from Umami. And excellent service. Again. The sushi was so fresh & well made, & the miso soup was spot on. They do it exactly as I ask for gluten-free & no sesame seeds. I have always had their food to go & they are fast, packaging it beautifully so cold is cold, and the soup is piping hot & so good. I tried a higher rated sushi place in the Omaha area but Umami quality has better miso soup & just as good & fresh sushi, & better prices. It's not fancy but it's nice for enjoying food with friends or solo.
