Teharu is a wonderfully inexpensive way to get to get a quick sushi fix, especially if you're looking to try new maki or nigiri without shelling out too much cash. Their sushi is not the greatest, but you get what you pay for, right?
If you want to try higher quality sushi, this is not the place you're looking for. They also don't have much variety, as most of the maki on the belt is some variation of California Roll with a different topping. It's a great place for beginners who haven't had sushi before, as they probably won't have had much experience with better sushi and won't need to pay too much for just a taste.
If you are coming in during the evening, be prepared to wait a good 15 to 20 minutes before being seated. Seating is limited and the place is always packed at these times. The staff has been attentive the three times I've been here, so I have nothing to complain about.
All in all, this place is good fun! I'll definitely be a regular here.
