I just seen your post asking about the Philadelphia quartett club. If this is the same one I am thinking about that's ran by P & P catering, I am having my wedding catered by them at one if there sister venues called "the towsend room". We went to see the quartett club when we where looking and it's really nice. They just re-did the entire inside of the space and I think they are even holding outdoor ceremonies as well.
I have never attended an event personal catered by p & p but I do live in the area and I have heard nothing but great things about the food and staff.
They are also on Facebook under p & p caterers. They show you pictures of each of there rooms set up for weddings and even upgrades they have done for weddings.
Best thing is they are really reasonable and and a family owned business.
Sorry if this is a book! But Goodluck planning everything!
