There's a whole spreadsheet here (you have to scroll waaaaaay down) with the average CS credit value, and maximum CS credit value (meaning, what you'd spend for the most expensive entree+beverage) for each CS that participates in the DDP. While the fact that the maximums include drinks makes it hard to assess whether it's the entree or the drink that's driving up the cost, the list might help identify other restaurants to check).

(FWIW, the places with the highest "maximum value" are as follows. I believe the prices include tax.)
