OK have not been to Vegas in 12 plus years and need at least 2 dinner spots - one really special and one can be a little more casual but with excellent food. We are 4 girls celebrating the big 40 and the one crunch is we have one vegan (does not need to be vegan restaurant but somewhere that may accomodate one vegan). Probably not a steakhouse. What are the best restaurants in your opinion? And somewhere amazing for the big celebration.
