I am always a fan of some Ru San's. Unfortunately at least most of the time the service is horrible. There are 2 waiters that are just awful. They are slow, they never refill your glass...its just bad.
The food on the other hand is great! I love their $1.50 sushi. It has a fun atmosphere and room for larger parties in the back. But if you do have a large party.. sometimes it may mean you'll be waiting for an hour for food. At least thats my experience with 2 birthday celebrations there.
If the service was quicker I'd give this place five stars, but that poor service kills it.
