As mentioned many times in reviews, Slice of Vegas is overpriced for what you get. The environment is fun and welcoming. It would be great for a group of friends and they have TV's all over so you can catch a game from any seat in the place. The hostess was friendly. The server was nice but seemed to be robotic in his approach.
It was not very busy when I dined here and service was mostly prompt. TV's were everywhere but the volume was not too loud so you can easily have conversations with your group while dining and watch the games.
The pizza was very good, NOT great but very good. Ordering a small (12') will set you back $20. It is good but not at all worth that price even being in Mandalay Place. The cocktails were well made. The presentation was weak but the flavor was perfect. The What's 6" and hard is cucumber Efiin and very refreshing. The Mob-a-rita is an Italian Margarita and also quite nice, They do pour a little heavy handed but the balance is still nice for the cocktails. $14 for cocktails and they are about 10 ounces.
The concept is good, the atmosphere is fun and the food is pretty good. The cocktails were the star but when considering the price of everything I can't give it more than 3 stars. It is nice to grab a bite before a show at the House of Blues or if you are shopping but it is not worth making a special trip to check out. Much better in concept than reality.
