The Cosmopolitan of Las Vegas has no less than 17 restaurants -- a number that doesn't seem so high once you consider its 2,995 rooms. Deciding where to eat can be a test for any visitor, but as a serious aficionado of Mexican food, I had my heart set on guacamole and tacos. The Cosmopolitan of Las Vegas had bigger ideas. What's the only thing better than Mexican food? Mexican and Chinese food.
