For the amount of money we paid for two for Sunday brunch (total of over $70) combined with the level of service (which was very poor) and quality of food (which was mediocre) we have definitely experienced better.
Don't get me wrong, the Cosmopolitan is a gorgeous new hotel sprouting with young people all over the place. The vibe is hip and cool and the "eye-candy" is everywhere.
The presentation of the food was alright, but what pissed me off was the young girl serving up the cuts of meat. I asked nicely for a thin slice of beef and she obliged by actually throwing the meat onto the plate like I was some sort of dog. No eye contact, no interaction, no "there you go, enjoy..." I went back for seconds and was even worse the second time around.
What the Cosmopolitan lacks is great customer service that Las Vegas is known for. That is what really keep the customers coming back (and that's for any business).
They need some more studying to do because we will NEVER return here.
