The quality of sushi here is between gas station sushi and your best grocery store sushi, but the price is better than both of those options. Most of the rolls only have one or two ingredients, and are very basic but it satisfies the sushi craving without dropping $50-60 on sushi for two. Teharu says that they're "fine dining" but I don't really see that. The seats at the sushi bar around the conveyor belt are very close together, and there's very few actual dining tables. I wouldn't consider any of this "fine dining" but to each their own, I guess. The only real con to Teharu is that their servers don't really have to serve you anything, so when you do need something they seem a bit rude. All in all, I think the super low price of food makes everything okay.
If you're a sushi snob and looking for top notch sushi, do not come here. Otherwise, if you don't really care as long as you don't get food poisoning, this is a decent place.
