It's been a while since we've eaten there. I remember the cars being tight for a pooh sized person back then. I think I've gained a few more lbs since then. Do I remember that there are some open cars with chairs rather than the bench seats? We are going to be eating there with someone who's' never experienced it before so I hate to ruin her experience. Do I have to request one of these open cars in advance or just when we get to the podium?
