Conveyor belt sushi restaurant. Sushi. On a conveyor belt. You really can't get much more simpler than that. At Teharu, you get what you pay for. Don't expect your dragon rolls to be spewing fire or your nigiri to be decorated with any garnishes or anything. If you want crazy fancy fish, go to RA; it's LITERALLY right down the road.
If you or any of your friends are new to the whole sushi thing, definitely try this place out. With the conveyor belt concept, you get to try out a little it of everything (About 3-4 pieces on average from around $1-2). Most of the rolls are pretty much modifications of the California Roll. If the belt looks empty, just try to steal an order sheet and give your waiter your order; *usually* you'll get all your stuff made.
Ignoring the insanely long lines on the weekends, the service is not bad. If you want to be seated down quicker with a bigger group, try coming in on a Thursday night around 5:30 or 6. Both conveyor belts are open then.
The service is really nothing to much to brag about. Pretty much all the food is self-served. If you want something from the waiters, ask for it. They can't read your mind. And they all work collaboratively(You don't have one specific waiter serving you in other words).
At the end of the meal, you're probably going to pay under $20 for sushi and leave full. Again, don't expect much. You get what you pay for.
