I have to stop by Lee's every time I'm in Vegas. There's a ton of them all over Cali but for some odd reason the sandwiches are much tastier at this location. Best part about it is there's never a long line when I go (I must be going at the right time!!)
This location is fairly large and spacious, it's always clean, staff is generally friendly, and the service is quick.
It's located in a strip mall not too far from the strip, the only problem I have sometimes is finding a cab back to my hotel unless I rent a car during my stay. Otherwise, it's great!
