Go to this one after 6pm. It's when they stop making sushi and bring the price down for every roll to $2. Also, they drop their prices for the packs. It's not a huge saving, but it's still better than nothing.
The sushi itself is full of the ingredient, so if you order salmon, you know you're going to get salmon throughout the entire roll and not just at one end. The mayonaise they use is tasty and their rice remains soft even after a few hours.
Try the purple or brown rice variants. Well worth the effort.
