I came here once for a dinner meal with a large party of non-vegetarians. Here's my Shima review.
Everyone else had wanted to eat the sushi, fish, and seafood dishes. I had a couple sides that were vegan suitable but don't remember the specific items... just seems to me that all the other diners were eating fish and sushi.
It's nice, though, that Shima advertise brown rice sushi. I'll have to go again and then update my review for happycow. Stay tuned.
Cons: slightly pricey
