I've been to Sapporo three times now and I'd have to say it's a solid 3.8 stars. Here's a little list of pros and cons:
Pros:
*Super clean! This is important in any restaurant, especially when raw fish are involved
*Very tasty sushi. I was leery of the quality given that this is almost buffet style restaurant but it's actually quite good
*Half off happy hour at night!
*Options like ramen and small plates for those looking to sample something other than sushi
*Friendly staff
*Low wait times if any
*Cool little robot trays that bring your food out when you order something from the kitchen
Cons:
*Lack of variety. I wish they'd mix it up from time to time
*Single occupant restroom
*Wait staff is friendly but never seems to freshen my beverage in a timely manner
*Neighborhood is a little sketchy. Not that they can do much about this one
