I am glad a bought a Groupon before coming here as it is just OK. The service when you arrive is below average for a Las Vegas buffet. They do not do a good job of seating their patrons and they also have poor service. We got the unlimited drinks with our meal, but in all reality we couldn't have more than two beverages as our server was nowhere to be found. The food was very mediocre. I thought the seafood was the best area of the buffet. They had some tasty options. The rest of the food seemed old and bland. I would try other places before coming here.
