You can go to fancy places and pay double the amount for the sushi, but you aren't gonna have an easy time finding sushi better than what they have at Lee's. My personal recommendations include: The pearl river roll, spicy tuna roll, spicy yellowtail roll, shrimp tempura roll, red snapper sushi or sashimi, even the california roll is pretty fantastic!
They do have a website, but it's hard to find by searching for it. (This site doesn't let me add a link, but just put a dot com at the end of: leesszechuanrestaurant )
Pros: The sushi is absolutely amazing!
Cons: The szechuan is good, but leaves a little to be desired.
