Buffalo Bill's is part of the 3 casino Primm Valley resort. It has a Western theme and the Desperado Roller Coaster. A very intense & fast roller coaster that will simply thrill the kids.
One of the main reasons we like Buffalo Bill's is that it is located right on the Cal/Nevada border and cuts the trip for Vegas style gambling by about 45 minutes. This also means you are only 45 minutes from Vegas for a day trip to the Strip or downtown.
Buffalo Bills has a nice arcade area for children and food court if you do not want to buffet.
