All of the TS restaurants in the parks are open for lunch. Outside the parks, the ones that do lunch are: B&C, Big River, ESPN, Concourse, Trail's End, GFC, Olivia's, Kona, Turf Club, WCC & YCG. The menus are very similar but not quite identical; there usually are a few items available at dinner that are not available at lunch and vice versa. As far getting a CS meal for a TS credit, I have no personal experience with that but as you can see some posters have reported being able to do this. I don't think you can *count on* being able to do this on the spur of the moment at whatever CS restaurant you happen to be at, probably because of differing computer system issues. I know I have read on here that some people were able to get TS credits converted to CS credits at their resort front desk on a 1 for 1 basis, but you would only want to do this if you were absolutely sure you would not be able to use those TS credits, because I'm pretty sure once such a conversion is made, it's not reversible.
