Good morning, I must admit I got a good chuckle out of your thread name...I know what you mean but as it is worded, I thought maybe you were looking for a place in Nevada!
All you can eat snow crab is very popular in the Disney area. At Disney, the Cape May buffet includes good crab legs on their great buffet. It is one of my favorites and as much as I like snow crab, I find myself eating a lot of the other things on their buffet and not hoarding the crab!
Outside of Disney I would stay away from the big all you can eat crab and lobster places unless you like chewy lobster and long lines and high hidden prices depending on the time you eat and what you include.
We have found some of the very good all you can eat crab legs are on the Chinese buffets. There are quite a few of them on the area and they always have coupons in the free books you find at Cstores. You might go the one closest to you and ask to see the buffet where you can check out the crab. You know to look for larger legs, nice and pink, and not a lot of dark coloring on the legs. Even the best restaurants can get shipments of frozen legs that vary a lot in quality so check it out.
Good Luck...Ted
