I've been to Toko Bistro twice now. Our conclusion is that it's better than Sushi Train.
There are more varieties of sushi and the prices are a little better. Both times we were there first thing at lunch time. They put out the boring stuff first, like inari (tofu), tamago (egg), fake crab, and tempura. Then comes a variety of California rolls, regular, jumbo, crispy (with tempura bits) and various dragon rolls. They do put a twist on all these by shredding the fake crab first and seasoning it with a bit of mayo, so adds a bit of flavour.
As the restaurant started to fill up, more varieties of sushi appeared, like gunkan sushi (the kind where the seaweed goes around the side) with a long thin cucumber strip replacing the nori seaweed. I tried the spicy scallop (made with small cooked bay scallops) and it was pretty good. The spider roll was so-so; while the crab itself was tasty, the roll had fake crab, as well as a dab of cream cheese (!) which I had to surgically remove.Tried the tuna nigiri, wasn't top notch. The rolls are definitely better. The place was almost full around 1pm, which is a good sign.
For dessert, we saw fruit salad, mochi, as well as cheesecake (still had frost on the berries!). BTW I made the wrong assumption in my previous post, they are Korean, not Chinese. Also, they did not have the plastic covers on them during the busy period. The chef did tell us what some of the rolls are before he put them down, otherwise we would have to look closely to figure out what some of them are.
