Event Ideas for Bar/Restaurant on The River?

I am part owner of a bar/restaurant in the CIncinnati area. Our basic theme is kind of a Key West, laid back kind of thing. But we would like to build more of a bar scene after dinner hours (9 - 10pm and later). Does anyone have any ideas for fun things and events to have to draw people's interest into coming there after dinner? We have live music on Fri and Sat night and we do cross-genre, not just one style of music.

Thank you in advance for any suggestions.Event Ideas for Bar/Restaurant on The River?
Well, in Cincy, outdoor drinking areas always seem to be pretty popular, so if you have the space, especially if you can have it looking out over the river (but appropriately fenced to keep the drunks from falling in the river), I think that would be a good thing. You should also set aside some space for Cornhole boards, you know how popular that is here. Maybe you could get some regular leagues going or something in the Cornhole. You can always add selling some Cigars, and put after dinner drinks like Martini's on the menu as well.
