Sorry, I had to laugh at the comparison between white fence farm and harolds. Certainly, i guess no different than russells and kenny's.
That said, I've only been to the mothership (off of rt 55 on the way to st. louis). It's a lot of fun in a really old fashioned way. The chicken dinner is very mid-west, similiar to what you might also get in Indianapolis. Like any good midwestern meal, there are pre-dinner relishes, something made from corn (the fritters) and decent prices. Another place were the sum is greater than the parts.
for whatever its worth, white fence farm would make a much better chow trip than oak park...
