Pricing and services: Margaritaville is a restaurant by day, music venue by late night. Their food is not particularly memorable; i.e. it's like what you'd find in typical chain restaurant, priced about the same to possibly a few dollars higher than you'd expect depending on the meal. They have a jambalaya that is pretty decent, about $20.
Their real claim to fame is some great drinks (i.e. strong) and the music is usually pretty good at night if you're looking for a casual place to hang out. If you are okay with the taste, the real drink you want to order is the 'perfect margarita.' It's a concoction of silver and gold tequilas, triple sec, orange curacao and lime juice. I personally order it made with Patron instead of the Margaritaville tequila. It is not the sugary crap margaritas you get from a place like Chilis or Applebees. It is STRONG, so take it slow lol.
From a group dining perspective, they run a bit high. My wife and I considered using them for our rehearsal dinner as they have private areas you can buy out on both the second floor (overlooking the strip, inside) and the third floor (overlooking the strip, outside). Before alcohol, I believe the second floor buyout was about $6000 minimum, and the group dining options came in about $40/per person minimum. Adding booze significantly increased it. We went elsewhere, but it was a very nice option from a location perspective.
