I almost gave up on buying food court sushi until I discovered "Sushi Shop". The sushi here is delicious especially the rolls. My favourite is the "Cherry Blossom" which has a really nice mix of crabmeat, fish eggs, shrimp, cream cheese wrapped with rice paper instead of seaweed. You might find it strange to have rolls wrapped with rice paper but it's actually really tasty. Although it's in a food court, the prices are a bit expensive. You'll easily end up paying about $15 including taxes. They do give you free miso soup.
I also just recently tried their Salmon Poke bowl and it's delicious. I think that I can eat this everyday. It's a mix of a good portion of salmon and avocado with tempura chips seasoned perfectly on rice. So yummy!
