I stopped in for a drink while killing time between some of the other attractions in Star Trek The Experience.
Romulan Ale is just blue beer. I'd hoped they'd come up with an interesting flavor. Given that the characters in the show defy the law to drink it, you'd think it must taste pretty amazing, but no, it tastes like popular cheap brand name beer you can buy anywhere.
The decor isn't pleasant. I'm not sure why anyone would want to sit around with a bunch of lumenglasses everywhere, in a darkish, noisy environment. And it's not like there's a big party all the time either.
I personally found the guys wandering around in alien costumes pretending to be real aliens to be cheezy.
