I would give this a solid 3.5 stars. We were looking for a place to get a small dinner and came across this while making our way through Ballys/Paris.
We were seated and attended to quickly. Our waitress was really nice, always made sure we had what we needed. We ordered a philly roll, crunch roll, and a couple pieces of octopus. Everything was really good and made well. Sushi came out quick, but not so quick you are wondering if its fresh. Sapporo's were nice and cold. A nice touch was they brought us a hot cup of green tea at the end of our meal.
I think they may suffer from being in such an odd area. We would definitely come back if we made it that far into Bally's again and were craving sushi.
