Filing a police report is probably the next legally expected step. Sadly, there's one more step the restaurant _should_ be taking here. The part in the thread where the place of business is scanning something off the IDs made me think of it. The reason they want the scan is as a way of taking a photo of proof of identity and residence to send the police after on a fraud report. Particularly if it's for multiple hundred dollars. That's still small claims court, but with that much evidence it's pretty cut and dry.
