You can't go wrong with anything from England or Germany, as far as I'm concerned. I also like black licorice and salted black licorice from Denmark. And stroopwafels (though you can get a decent sub for that at Aldi while they have their German Oktoberfest stuff in stock (like now).
When I can get there, I do a lot of shopping for spices and specialty items in their Asian, Mexican and Indian foods departments.
There are now 2 Jungle Jim locations in Cinci. I've only been to the original, and that's the one I would recommend:
Jungle Jim’s International Market Fairfield - 5440 Dixie Hwy, Fairfield, Ohio 45014. It's definitely a trip. And it can take hours to go through, if you like to shop and look at things. (And make sure to take a trip to the "world famous" restrooms near/in the liquor department.)
