Yume is ok. Not great, but not bad. The worst thing about this place is their inaccuracy. The sushi you do get is usually pretty tasty, but the last four, yes, FOUR, times we've either ordered take-out or dined it, they've screwed something up or missed part of our order entirely. Each of these last four times I'd ordered salmon sashimi and never got it. It's definitely a problem when you order take-out as there's no real way to check it's all there before you leave with it.
The sushi is good. Just make sure you actually get what you pay for so you aren't ripped off a few extra dollars.
