I am probably forgetting something but that gives you an idea. We ate most of our meals there and would grab things here and there in the parks occasionally. I would say the quality was pretty good if not better than most of the food in the parks. It was nice to sit and relax and have a beer or a glass of wine in a mostly quiet atmosphere. We would load up on water bottles every morning and reload in the afternoon.
If you pay for the concierge level it makes sense to use the lounge as much as possible or there really isnt much sense in paying the premium for the other perks. Dont get me wrong, it was great the way they treat you at that level and being able to get DVDs for the kids was nice, but those alone are not worth the extra cost. We have kids 6 and 9, so we would come back to the hotel a couple times to relax and recharge. If we had older kids who wanted to spend the entire time in the park, I probably wouldnt do the concierge level unless they were old enough to send off on their own.
Hope that helps.
