We like the fried rice at Yak & Yeti - it's a snack credit. Also samosas and falafel at Mr. Kamal's at DAK (when it's open) are both snack credits.
If you have CS meals left over (we did last trip) what we did was have the cashier at our gift shop at Pop figure out how many we had, then we bought a bunch of bags of candy & trail mix with them (ended up with 14 of them). 3 per CS credit. Better to do that than let them go to waste. This trip, we'll try to use them up more, though!
