Know what you're getting into.
For me, there are 2 different categories that I put sushi restaurants into:
Either A) the old school, traditional places that honor the old techniques and the true artform of sushi (where sitting at the bar and ordering nigiri by the piece is what you want to do)
B) A trendier spot that's going to be more focused on creative rolls.
For me, Crave falls into category B. That's not a bad thing by any stretch, but it's just knowing what their strong suit is. I honestly don't think that the nigiri are of particular note here, so in my opinion that's not where I'd spend my money.
The rolls are fun and creative, so it's more what I would consider Japanese fushion than true sushi.
If that's what you're looking for, Crave is definitely a great spot.
The techno music and contemporary decor are a little off-putting, so I probably wouldn't enjoy it as much if the dining room was packed full of people. All the hard surfaces would result in an atmosphere that would be too noisy for the meal to be enjoyable.
