We did PM 3 times and Maya Grill twice last year (and I picked up a Sandwich at the Grab n' go place for my friend...wow we ate at the resort a lot....). At any rate:
Maya Grill. The menu has changed since we went in September, but we both really enjoyed our meals there (so much that the 2nd time wasn't planned, it was a 6pm walk-up during
free dining 
). It was quiet and our servers were great both times.
Pepper Market. Wasn't impressed with breakfast, but both lunch and dinner were good. Again, service was very good (except that breakfast). I had steak ranchero for one meal, and... um, something else for the other (likely some sort of beef dish, I'm a bit picky

). Friend had some stuff that I can't remember.
Grab n' Go. Forgot why I picked stuff up here one night, probably the night we didn't have dinner planned /shrug, at any rate, picked up some sort of chicken sandwich that was deemed quite good as well. No personal experience, as I just snacked on stuff we bought at
WalMart that night.
I'll be back there in a month (exactly today!), this time I'm planning on the new breakfast menu at Maya Grill
