I wanted to like it, I really did.  Reasonably priced sushi, convenient location, menu with all the flavors of the rainbow (roll)?  I didn't even mind the former Pizza Hut layout.  What I DID mind was the 50 minute wait for a to-go order to be completed; when I called to place the order, I was told it would take 25 minutes.  We probably showed up after 30, and then proceeded to sit on a bench for another 20 minutes until the order was complete.  By the time we got our three (yes, only three) rolls home, the spider roll was cold and mushy.  The other two were fine (spicy salmon and rainbow), but after the long wait I think I was maybe just glad to be eating anything.  Provided you don't mind waiting for them to catch, debone and descale, and then finally make your dinner, Koishi is a decent option... but there's many other choices around town.
