I think that White Castle might be an aquired taste like Cincinnati Chili and good Scotch and I do say them in the same breath...
When I was little and I suspect poor, we would be driven to Bexley in Columbus, Ohio, about three times a year to buy a bag of White Castles. My cousin and I could hardly wait to taste those little sandwiches with the oniony smell coming from that bag and the little cardboard containers that looked like castles. Cousin Ronnie had his mom take the pickle off of his.
Also remember the very rare visits to Galls ice cream on Lockbourne Road in the South end for a milkshake.
