They don't know how to estimate wait time
I have to agree with the ""HIGHLY DISAPPOINTED..... If you go, make a reservation"" wish I had read that before we stopped in at the Orland Park location for dinner. That review was written in 2008, but could have been now (they are still the same).
DO NOT JUST STOP IN
We were told 30-35 minute wait (for a table for 3). After an hour, we still weren't seated and not likely to for another 1/2 hour or more the way things were moving. We gave up and walked out. When we left, they were telling people the wait was an hour or less. Ha! Those people will be there two or three hours.
We won't be going back.
