I'd read some great reviews about Carson's Kitchen and it lived up to expectations. It was a little tricky to find with a very understated street facade but we got there in the end. Had to wait 15 minutes for a table but the time was well spent at the bar and checking out meals ordered by other diners. Our own selection was fantastic and the strip loin steak was to die for. Very reasonably priced and good sized portions. The only slight negative is that the food is delivered as it's cooked so you're not likely to be able to all eat at the same time if you're in a group.
Overall I would highly recommend and definitely go back next time I'm visiting Vegas.
