This has probably been asked before, but how do room charges at the Linq work? Can you do a room charge at all the restaurants on the promenade (yardhouse, tilted kilt, etc)? Or only the restaurants actually inside the casino? Thx... EDIT: I just looked at the "earn and redeem" page on the TR website....the only Linq restaurants listed as accepting RCs are Guy Fieris, HHAGG, and Nook. Does this mean they are the only ones that accept a room charge?
