The celebrity chef’s portfolio includes The Seafood Restaurant, Padstow and Rick Stein, Barnes.
The group also reported 717 retail transactions from four outlets including Stein’s Gift Shop, Deli, Fishmongers and Patisserie.
Chef director, Jack Stein, said: “It was such a buzz being back in the kitchen this weekend. We’re really happy with how it went, our customers all respected social distancing and were clearly as happy to be back as we were.
“Safety was our number one priority and our new measures, from one way systems and table spacing to adding new fully sterilised and sealed cutlery pouches to every table, proved to be a great success.”
Charlie Stein, wine and spirit advisor added: “Bookings are looking good for the remainder of the summer season, however we’re not naive enough to think the next few months will be plain sailing. To those people who can no longer go abroad for their usual summer holiday, we would love to welcome you down in Cornwall.”
