We love PBH and their club level is great! It's located right off the lobby next to the American Bar. I've never seen it overly crowded and there is always plenty of seating. The staff is wonderful and are very helpful when it comes to any questions you may have both hotel and park related.
As far as food offerings we find PBH far above Disney where we have stayed at both AKL and Contemporary (Atrium and Tower) club many times. A quick comment about the staff again. IMO they are comparable to the staff at the Contemporary which we think are amazing, AKL, not so much.
Breakfast has a hot egg dish, a meat such as bacon, sausage etc. potatoes, pastries, muffins, breads, english muffins, cereals both hot and cold with add-ins, lots of fresh fruit, juices, chocolate and white milk, hot chocolate, teas and of course coffee with syrups. My family loves that hot items are available. Afternoon snacks are the standard and there is a beverage fridge that has sodas etc to grab. Water and fresh fruit are always available. As far as dinner every night there are cheeses, vegetables, crackers,breads, olives etc. plus a couple of hot dishes and a salad choice. Desserts are the standard cookies, cakes, mousses, cobblers, parfaits etc. Three to four are offered nightly. Beer and wine are complimentary, mixed drinks are charged. We don't but I'm sure people could make a meal out of dinner.
If you have any other questions feel free to ask.
