We stayed at CSR with our Grand Gathering last December for a week and ate at the Pepper Market a total of 4 times; each time was a bad experience. They were staff was generally unfriendly (I've never felt like more of a nuisance to someone than when I was trying to explain to the cook that I only wanted 1/2 the amount of cheese - one handful is enough, thanks - he was going to put on my steak quesadilla - the nerve of me!). The unique punch-card ordering system, while interesting, was more a pain-in-the-neck than the traditional method. Cleanliness; utensils and plates were always clean, but as a whole the dining room felt like it could use a good scrub down.
And my least favorite part of the Pepper Market; The steady pounding of techno music from the dance club it shares the common area with - REALLY disrupts the ambiance of the resort IMO and creates an obnoxious environment at night.
The food was pretty decent and portion size was very fair, but I ended up avoiding the Pepper Market for the last 3 days of the trip, just grabbed a sandwich and juice at Cafe Rix.
