Well, like... you can buy pretty much anything. Even things you wouldn't expect. Food, drinks and clothes are the obvious things, and you kinda get what you pay for with those. Whether or not the food and drinks are spiked varies.

Even when it causes horny effects, the quality is pretty good.

You can also buy items from home, even if you didn't have them with you before you arrived. Some people with abilities might find that they've been suppressed, and they can get full use back for a price. Even wilder, this place can give powers to people who didn't have any.
