I've stayed at the Cosmo several times and I always stop by here, it can get pretty crowded around peak times, but anything worth doing in Vegas is the same.
The Food:
The last time I was here I had the philly eggroll and the Nom Nom burger. The Philly eggroll was actually really tasty and flavorful and I would definitely get it again. The Nom Nom burger (burger with chips and cheese inside) was on the salty side for me.
The Highlight:
The highlight of this place every single time is the milkshakes. Whether you get them alcoholic or non-alcoholic, they are absolutely delicious. I tried the drunken monkey, the banana cream pie, and the fat boi, and they are all soooooo good. I only wish they were only 24/7 so I can grab one after leaving the club. Thumbs up!
