My understanding is that if you have any problems, you ask either the hotel reception, or the restaurant if they allow room charges, and if they do, you should be able to get credit.
Successfully done this at various properties, mostly without problems (the excellent Japanese restaurant at the LC SF used to be a problem, but some very insistent brit educated them, and I've never had a problem since

)
Only supposed to post as points - but sometimes hotels make mistakes on these transactions, tragically

I dine at a St Regis all the time and they fill out a voucher that resembles an old-school credit card slip, give me a receipt, and then I get credit. If the restaurant is not OWNED by THAT HOTEL, you get zero credit, however.
