Well, let me rephrase the not cheap thing. It's not McDonald's cheap, but you don't have to run up a $100 tab, either. You can probably get out of there for $20-25 if you want to.
Now, if you want to have cocktails, eat the most expensive sushi on the list, and so on, then it gets pricey. I did that one time back in the good ole days of the dot com bubble, and was rewarded with a bill that would now get my ass kicked if I submitted it for reimbursement.
