Was in Vegas last year for New Year with 16 of my mates. It was well cool. Go to the Irish theme bar in New York New York. They had an amazing live band on every night when I was there.
That's how you do Vegas Ian...go in mob handed! I'm fairly sure the Irish bar's getting a refit at the moment, although I was really tired when I walked past.
Next time I'm here, it'll definitely be with some of the guys (one or two love a wee bet)
