You would need to get a US number from a SIP/VOIP provider, then just have the restaurant forward their number to the number you registered. two things though, you will get ALL of their calls using this method, so the restaurant would essentially not have a way to take calls unless they install a second line or get a second DID. Then, as others have mentioned, the call quality will probably be crap.
