I was visiting my mom who lives in Vegas (a retired stripper) and she recommended this for dinner based on her prior experience. Be sure to pick up a "Boarding Pass" player awards card in the casino before getting in line to save you $2.00 per person.
A good selection of foods with salads, desserts, American, Italian, Mexican, Mongolian BBQ, & Chinese/Asian. Crab legs are now extra per the cashier. She was a little hard to understand. I thought she was asking if I wanted frog legs, ugh, not so much. The Mongolian BBQ will cook to order a variety of and the Chinese had the best quality consistency among their offerings.
Definitely worth the drive and a little more refined than the usual Las Vegas Strip Buffet. Green Valley Ranch Resort is adjacent to a large shopping center with what appeared to be upper middle retailers.
