Love this place! We went on out last trip to Vegas in May 2012. Nice open atmosphere near the table games (they leave the doors open, so you get nice fresh air.) The dealers were great, very friendly and helpful. I was still pretty new to the game of craps when we went but they had no problem showing me the game, helping me out, and joking around. Really quick drink service too.
The 5 o'clock somewhere bar was great. They have a "reverse happy hour" which was really cool. We had trouble adjusting to the time zone change (we're from the east coast) so we'd wake up every morning at 4 or 5am! We'd just head down to the bar, get some $5 margaritas during happy hour, and play some craps before the table got too busy. It was great!
The only reason I didn't give it 5 stars was because of the lack of the type of table games I like. It looked like they had plenty of blackjack tables, but only 1 roulette table and 1 craps table. There were a few times when I wanted to play but couldn't because the ONE table was full.
Still, it was a great time. We'll be back to Vegas in May 2013 for our honeymoon and plan to stay at the Flamingo so we can spend more time at the Margaritaville casino and 5 o'clock somewhere bar! :)
