I can only tell you our experience. We have tried going to Manny's around 4-00PM to avoid the queue.
Didn't work for us, as soon as we drove into the car park we realised it was a bad decision.The car cark was nearly full and queues had already formed outside the door. At first we thought that everyone was waiting for Manny's doors to open. No such luck inside was just as bad. We waited over a hour to be seated which was less than other visits. Also we chose a night when kida eat for free which probably made matters worse.[msnsmile2]
