At my little hotel on the Strip (no longer Cosmopolitan, btw) we have an Employee Dining Room. It's... well... it would get zero stars on Yelp. So sometimes we just can't hack it, and call in for some more-edible options. One of those places is Kung Fu. It had some good reviews and a full menu online, so we gave it a try.
It's exceptionally pleasing! Of course, I had to go with Pineapple Fried Rice (my favorite!) and theirs comes in huge portions with chicken, pork, shrimp, and crab! What a catch! (You see what I did there?) My coworker went with the pad thai and she liked it.
The best part is that delivery is in pretty reasonable time, and they deliver anywhere to the strip. It's a pretty good option, especially if you just want to chill in your hotel room before going out.
