I've been to both Wolfgang Puck Express and to Earl of Sandwich and they are both simply phenomonal! I don't think you could go wrong with either one - they both have great food, it's a great use of a CS credit and the menus at both places are so different of each other, you're bound to find something that you like either place.
As far as TS goes, I haven't been many places there (only been to RFC, Planet Hollywood and Cap'n Jacks). Out of those 3, I'd choose RFC only for the atmosphere. Stay as far away as possible from Cap'n Jacks. I've tried it twice and both times I left feeling much less than satisfied with both the food and service. Maybe I caught them on bad nights but I'd rather just try something new.
