I've been going to Charlie's for years, but never had the fortitude to try the "Fatburger." Their burgers are very good, not what one gets at The Palm, but very good nonetheless. In fact, I've never had anything there I've not enjoyed.
I could go on and make this "review" quite long, but this is just another Las Vegas pub, albeit one with good food and that's "reliable" in terms of food. But, it's just a pub. That said, I think Vegas has the most consistently good pub food that I've ever experienced. Now I live near the Outside Inn -- and feel the same way about it. Good food and no mistakes with regard to ordering anyting.
