Argosy is about what you'd expect of a riverboat casino - not exactly high class and kind of small. Of course, I'm comparing it to the casinos in Vegas, and, well, there's really no comparison there. I think there's plenty to do there with respect to gambling - they have a poker room, they have slots, they have table games like blackjack, and so on and so forth. However, I'd have to say that, for a bachelor party, it won't be the most exciting atmosphere. Every time I've been there (which is about 10 times), there hasn't been much scenery. The patrons tend to be older and, well, hick-ish. No that there's anything wrong with that, it's just not the type of crowd I'd like to spend my last night of singlehood with, you know? Similarly, I don't know of many clubs around that area - in fact, the Argosy is kind of in the middle of nowhere.
In sum, the Argosy has enough to keep gamblers satisfied for a few hours, but the scenery is a little lacking.
