They make you do this at most sit down restaurants in NOLA. I was told that it was to make it easier for covid contact tracing in case of outbreak.
Under the city’s current Covid-19 restrictions, contact tracing is required by restaurants. “Food service establishments licensed as standard restaurants under the CZO that provide table service will be required to utilize a reservation system to track names and phone numbers of customers, keep this information for 21 days, and provide it to LDH if requested for contact tracing purposes.” https://ready.nola.gov/incident/coronavirus/safe-reopening/#362
Blame the city's local ordinances, not the restaurant establishment.
