I've eaten at Umami at least ten times. Why do I go back? Here's why:
(1) Pork buns. These are the best I've had. Try for yourself: have the pork buns at Graze (or wherever you eat pork buns), and then have them at Umami. Umami's are better. I'm not trying to start a pork bun war, I'm just sayin'.
(2) Tonkotsu ramen. This is Umami's signature ramen, so rich and delicious. And that egg everyone's talking about? Get yourself one. De.Lish.Us.
I've never lived in Japan, so I have no idea how Umami's food stacks up against the ramen served in traditional Japanese homes. But I do know this: last year, I was seriously considering becoming vegan, full time. But I couldn't do it, because I knew I'd never have Umami's pork buns or tonkotsu again.
True story. Go, enjoy yourself.
