Translation:– Excuse me, there is a mistake in the check. – My deepest apologies. Just a moment!
Yes, in restaurants only, we call the bill a "check". For example if you want to ask the waiter to bring you the bill, you say "check, please." Basically we only say that regarding bills in restaurants... elsewhere, we call a bill a bill. It is an oddity (because in almost every other context, the thing you pay is a bill and a check is something different) but for a restaurant conversation it is 100% correct in American English.
