CSR has a food court called the Pepper Market. It has a wide variety of options including steak, pasta, a wok area, deli, soup and Mexican. You do have to pay an automatic 10% gratuity to eat inside, you can request a to go order and eat outside and avoid the 10% gratuity. The food is very good. They also have Siesta's out by the main pool and that is mostly quick serve type stuff (hot dogs, wrap, burger stuff like that). Then there is Cafe Rix which has some sandwiches, and salads and panninis. The full service place is Maya Grill which is pretty pricey but I thought it was very good. And last but not least CSR has room service and is the only moderate to offer that. Pepper Market, Cafe Rix and Maya Grill all serve breakfast.
CBR has a much more standard food court. They have several stations, and its your basic food court fare. They have burger station, pizza and pasta station a grill area and a grab and go area that has sandwiches and other ready made items. CBR also has Shutters for their full service restaurant, we enjoyed dinner there one night, its sort of pricey like Maya Grill and I thought it was better than Maya Grill. CBR has pizza delivery service to the room but no room service like CSR does. The food court also serves breakfast. Shutters does not.
So CSR has a lot more (way more) in the way of choices but if you just need a quick burger or breakfast the food court at CBR is great. If I was going to eat a lot of my meals at my resort, I'd pick CSR. Its a convention resort so many of their guests do stay right there for days on end so they need lots of choices. But again, the food court at CBR was very good for our needs and I did think thier full service restaurant was better than CSR's.
