We stayed at AM on our first trip and had a blast there. I'm afraid the food options aren't as good as say at Polynesian or WL, but you will do fine.
We're all Vegetarians so there wasn't a heck of a lot for us, but the Pizza place is great. They also have a nice Pasta selection, big breakfast and the typical burgers etc. We walked over to Music resort for a change one night and found they had a totally different menu. It's just across the way, maybe 5 minutes on foot. I also think there is a McD's nearby if you're into that. All in all they had a decent selection- nice chilled selection of sandwhiches and wraps and has some good Mexican one night. I think there is some change to it every so often.
I believe the drink station was 24hrs. They have a decent patio bar and you can purchase beer, wine etc in the gift shop. I always found breakfast to be expensive at WDW so we tend to bring sound bagels, muffins etc. either in the car or when we have flown we asked the driver to stop at Publix. AM has several toaster in the common eating area where you can toast whatever you please and there is a hot water dispenser on the drink station if you want to make oatmeal or baby cereal.
Hope this helps
