Prosperity Social Club is a clever update of a retro Polish social club. Clever, in that the only aspect of the joint that actually seems updated is the menu, while the bar itself seems to have been perfectly preserved in time. I lived in Cleveland in the 80s and 90s for a dozen years, and I never saw any bar or restaurant that screams Cleveland more than this gem.
Our party of four was there for brunch, and all of us were impressed with the straight-from-the-70s beer hall decor, as well as with the innovative menu that featured such delicious items as biscuits & gravy & fried chicken; polish breakfast with scrambled eggs, kielbasa, & pierogies; and the C-Town Sausage sandwich with andouille sausage & roasted banana peppers. A full bar was available and we partook of the piquant and spicy bloody Marys along side our coffees.
Service was impeccable, and the only thing that kept our experience from being five star was the annoyingly blase couple who let their twin toddlers have the run of the place with almost no supervision. I love kids, but toddlers do not belong in bars, especially if their parents aren't looking after them.
