I go to Jungle Jim's every time I'm in Cincinnati. While, conceivably, you could find most of the things they sell there in Chicagoland, you'd have to go all over town.
Basically, it is a one-stop ethnic superstore.
I have certainly found soda pop there that I haven't seen here. Also British and Dutch products that are hard to find here. I usually spot some item in the produce department that I don't recognize at all. I often wind up buying some kind of cheese, too.
It's really worth spending the time to shop all the aisles, particularly the different ethnic areas at the back of the store.
If you are looking for Ohio regional goods, like goetta, I don't know if this is the best place. But they probably have that, too. While you're in Cinti, be sure to stop at Graeter's for ice cream and opera creams.
