$4 for an omakase sampler seems financially infeasible even for grocery store sushi. Jubilee Marketplace has an array of affordable sushi options amongst their other delightful prepared food. I also got a salmon maki for $9 to supplement the 6 piece omakase. It was all top tier for supermarket sushi though you can never escape the weird cold texture of refrigerated rice. Whoever figures that out may become the first respectable billionaire.
