To be fair, I ordered from GrubHub so my experience was only with their takeout.
And it was not that great.
I waited an hour and 45 mins for my food to show up. I ordered crispy tofu and miso ramen.
By the time it showed up the crispy tofu had turned into a gelatinous blob. The Miso Ramen, which I was really looking forward to was okay... my problem was that the broth was a greasy mess. I've never actually had Ramen before that was served in a broth this greasy. It was so greasy that I discovered quickly that it was inedible.
It was like making a broth out of just pan drippings from a Thanksgiving turkey.
Fortunately I keep my own miso paste on hand so I just made my own broth.
I probably won't order from Umai again.
