On a recent trip to Las Vegas we stayed at The Cosmo for two nights. I had stayed there once before and wasn't a fan but had a much better experience this time around. Our room was beautiful. It had a balcony and a huge tub over looking a great view of Vegas. The room was very nicely decorated with a Jonathan Adler feel.
The gym had great equipment and a nice view of the Bellagio fountains. But they did not offer bottled water, only a water machine with cups, which is not easy to drink while working out.
There aren't that many breakfast options, which I found frustrating. The main breakfast restaurant had a long wait each morning and the grab and go food only consisted of pastries and coffees. Nothing healthy or fresh.
The restaurant options in the hotel are quite vast for lunch and dinner. Milos is by far my favorite for lunch and dinner. We also had a nice lunch at China Poblano.
*Tip: Milos offers food to go, so if you want to eat dinner in your car on your way back to LA get Milos to go rather than having to stop for fast food!
