I went to Flatlander's in Lincolnshire a few times when my wife was going to graduate school there. I can't say that there was anything necessarily bad about the place, but I will say that I was never overly impressed.
It seemed to me that the whole place was less than the sum of its parts. What I mean by that is that they seemed to have a lot going for them-- great location, nice building, excellent concept... but nothing was really special about it. Overpriced food, slow and not very friendly bartenders, beer that was forgetable (for lack of a better description-- I truly can't remember any of the beer I drank there).
On the other hand, I never really found anywhere else around there that was better.
