Only one problem, really...
I only have one gripe about this one: the upper-left of the display which shows what sushi you're getting after your current one is MUCH more of an eye-grabber than the little chef holding the current sushi in the middle. There must have been a dozen different times that I completely botched a chain because the display confused me about which one was coming next. Once I realized what was going on I could start correcting for it, so it does work if you're not retarded like me... I guess my point is that it's just NOT a very intuitive display. Everything else is fine, though.
