Can anyone recommend a really fun strip club? And, can anyone recommend a really sexy, fun place for happy hour/dinner?  Thanks for your input.

Regarding a "fun" strip club, I think you need to be a bit more specific regarding fun. A guy's and a woman's view of fun aren't always the same.  
I'll try to help you the best I can. Christies and maybe Diamonds in the flats will have the best looking women with Christie's being slightly more hands on. Both are also nice upscale clubs.  
There are several clubs on Brookpark rd near the airport but most are dives. There are a couple other clubs scattered in the area, the best bets would be Crazy Horse on the eastside and it's sister Crazy Horse Men's SE of downtown. There's also a Hustler club next to Diamonds in the flats and at times that could be your best bet.  
Best of the bunch IMO, Christies.

Hope this means you'll be visiting Cleveland!
