I had my first Vegas dinner here, just to observe the strangeness of the locale. The Hilton is way off the strip, and the Star Trek Experience is really quite dated. The service was not that great - the food wasn't anything special. I ordered a "Sulu Toss" with chicken and shrimp - granted it was a lot of food, and looked interesting - a dome of rice with two huge breadsticks sticking out of it, and the stirfry in a moat around it, while my friend Mary ordered the Hamborger - which was just ok.
The drinks looked interesting - they had a huge shark-bowl like drink that had 10 shots worth of alcohol in it. I ordered myself one of their non alcoholic drinks (wit Strawberry, Banana, and Pina Colada) and asked them to put some rum in it. It was ok.
The only draw is the Klingon that walks around and mocks you and your dead food. He definitely seemed bored with his job (possible Elvis impersonator reject?) but nonetheless, you can get your picture taken with him.
