Nothing like a humongous margarita to add to the heartburn that has already been raging off mass amounts of pizza, booze and sleep deprivation. SO WORTH IT.
Margaritaville is the shizniz. The only lame part is having to down your drink before entering (and with 32oz American beer just bought on the street 10 min beforehand, this is no easy feat). But alas, a few gulps later, we walked into a lively atmosphere with sticky floors and fantastic music. Almost like a nightclub, but free and with much less douchebaggery, Margaritaville is a fantastic place to spend an hour or so, before hitting up the next spot on the strip. The margaritas are super tasty, and expensive to boot. But it's Vegas, so if you don't expect it it's your own damn fault.
Go for the margaritas. Go for the music. Go for JIMMY.
