You don't have to walk outside from BC to access either the Marketplace at BC or the Market at YC. Both have hot food options, though I do prefer the menu items at the Market at YC.
I think the points I tried to make are being missed -- perhaps I wasn't clear. The lounges are small, they are not designed for children (nor are the menus), many parents do not want to take their children into bars, particularly at a conference hotel where there is more adult conversation than you would normally experience at a WDW resort; tables are not cleared as people finish eating in a lounge as people may be there for the night with the group they are socializing with. The BC, in particular, attracts families, but the BC/YC lounges are geared to adults on the conference circuit. The counter service options also assume that the conference guests are getting fed through their conference experience, so they are not really looking for a decent offer of varied food in the evenings.No one would even bat an eye at a family with children eating in one of the lounge areas and if they do, who cares, children are allowed!
I'm not really aiming to start a war on this, I was just trying to provide some advice to the OP who was worrying about BC dining options based upon my experience of the resort and some of the dining limitations I think the resorts have.
