I think one's feelings about Artist's Palette will be influenced by expectations. If you are expecting an elegant, full service dining experience- you should be very disappointed. If you are expecting a place to grab a burger and fries - you may also be disappointed.
Artist's Palette does offer made-to-order options from the limited menu and the chef behind the counter. There are flatbread pizzas, meatloaf, chicken and beef selections, etc. on a changing basis depending on what's offered at the time you visit. The seating area is certainly cheery and comfortable, but still not anything close to a full-service experience. The resort store is also located within the same general space. There are drink options including wines and refrigerated items like cold sandwiches and salads. Most items can be enjoyed on-site or can easily be carried back to your villa at the resort.
We enjoyed the few meals we've tried there, but in general have a neutral feeling about the experience. Not personally being a food court proponent- I found Artist's Palette certainly to be a step above the typical mall or moderate resort food-court experience ... but ... it is definitely a step (or three) below dining at the Yachtsman's Steakhouse at YC, Artist's Point at WL or even Olivia's at OKW. There are many great restaurants at DD to choose from and those will serve the SSR guest's well, IMO- with Artist's Palette as an appropriate option for eating quickly and close to their villa.
