Restaurant @ The Cosmopolitan of Las Vegas
"Scott Elliott"
We were in Vegas with our HS/college age kids and just wandered in here when we were hungry. Wow. The burgers are delicious but the milkshakes are full on amazing. They are hard to describe. One came with a full size ice cream cookie in it. They are huge so you might want to get them to split. (Glad that's what my wife and I did.) The kids loved them so much they insisted on returning for shakes again the next night. You can do that BTW. They have a bar area where you can get drinks or a dining room for dinner. Also you can get the milkshakes with booze in them, which sounded delicious, in case you are NOT traveling with the family!
