I like McCarran. Every time I've gone through here (4 times now), it's been super fast, clean, and easy on the eyes. There's also free wireless here, which, although I've never used it, is a huge boon.
I also like the food here, although selection is limited. There's a Jody Maroni's Sausage Kingdom (actually good!) and Ruby's Dinette, which I like. There's also TCBY. Overall, I've only had pleasant experiences here. Plus the boy and I won $40 here on slot machines. Woot woot!
