We usually find our way to Margaritaville on every visit to Las Vegas. It is a fun drinking and dining establishment.
Fun - the place is always crowded and loud, in a good way. There is almost always a live band in the evening. Folks get on the dance floor. Large groups for birthdays or bachelorette parties keep the place lively. I have seen staffers on stilts and making balloon sculptures for guests. It is almost like stepping into Mardi Gras. This is not a place for quiet conversation with your table-mates. But, you probably already spent too much time talking to them already!
Drinking - the bar has an impressive list of tequila selections. The house margarita is very good (and very strong). Buffett fans will find references to songs and stories in the names of the drinks. The wait staff is attentive and you never need to wait long for a refill. Drinks are served in plastic to-go cups for your walk back to your hotel.
Dining - Like many other reviewers, we normally have the Volcano Nachos. The serving is huge, probably enough for 3-4 people. There are other items on the menu, but the nachos are so good, we have never had a reason to try anything else. Plus, the food prices are very reasonable for the Strip.
We showed up around 10:00 pm on a Sunday and had to wait about 30 minutes for a table. This is not abnormal at this time of night. However, this was not a problem as there is a gift shop to browse and the Margaritaville casino (part of the Flamingo) is close by if you have a longer wait.
Overall, Margaritaville is a great place for fun, late-night dining in Las Vegas. We will certainly be back on our next trip!
