Today actually was my 2nd visit to Cafe Wasabi, the place is pretty interesting. Nice decor, small, with a BIG selection of rolls. (they have pictures of all of their rolls and rice dishes in store) They are not the 'normal' Japanese restaurant you visited, but more of a mixture of different kinds of foods, Japanese and Korean are the main kinds, then they have a small selection of sandwiches and even panini (Italian??), salads, and sake. (that's why it's called Cafe? )
You pay right after ordering, like in a fast food restaurant, then go fill your own fountain drink, seat, they'll bring the food to you. I've tried the Grand Canyon roll, the Unagi Crunch roll, and the Udon. The food actually taste good, not that spectacular, but with the price I'm paying, I'm not about to complain!
I think this could be a place for your casual lunch/dinner with friends, cheap price, but decent food!
