This place was EXCELLENT!  We were on the hunt for a great steakhouse and we definitely found it here.  The food and drinks were excellent and there were many options to choose from.  One thing I find in many upscale steakhouses is a somewhat limited menu with only a handful of entrees and appetizers to choose from.  Delmoico's has an expansive menu and everything was delicious.  the atmosphere and food made for a great night out... definitely try if you are looking for a nice night out (for steak) in Vegas!
