I booked lunch for 25 for a family party at a local restaurant. I made the booking by phone on 8 October for 26 April. I phoned today to firm up to be told the restaurant is now being run by the owners and that I had made the booking with the people who were leasing the restaurant at that time and that the owners had not been made aware of the booking at the handover and they cannot take us. It is almost impossible to get a venue for a lunch on that day - have the owners any responsibility to me?
