“We have always been honored to welcome you and will always be to welcome you again,” The Peninsula Hotel replied

Serena Williams expressed her disappointment with one fine dining restaurant in Paris.

On Monday, August 5, the retired tennis player revealed on X (formerly known as Twitter) that The Peninsula Hotel in Paris denied her and her children with husband Alexis Ohanian — Alexis Olympia Jr., 6, and Adira River, 11 months — a table on Monday.

“Yikes @PeninsulaParis I’ve been denied access to rooftop to eat in a empty restaurant of nicer places but never with my kids,” she wrote. “Always a first. #Olympic2024.”

The restaurant then replied to the four-time Olympic gold medalist, 42.

“Dear Mrs. Williams, Please accept our deepest apologies for the disappointment you encountered tonight. Unfortunately, our rooftop bar was indeed fully booked and the only unoccupied tables you saw belonged to our gourmet restaurant, L’Oiseau Blanc, which was fully reserved,” read the company’s first reply on Monday.

“We have always been honored to welcome you and will always be to welcome you again. The Peninsula Paris,” a second post followed.

Representatives for Williams and The Peninsula Paris did not immediately respond to PEOPLE’s request for more information on Monday.

An employee at L’Oiseau Blanc, Maxime Mannevy, told Variety that Williams looked “unrecognizable” when she arrived at the restaurant with another woman and a stroller.

“When she came there were only two tables available and they had been reserved by clients of the hotel,” said Mannevy, who told the outlet she was not working when Williams was at the restaurant. “My colleague didn’t recognize her and feels terrible, but he told her what he would have told any other client, which is to wait downstairs in the bar for a table to become available. That was absolutely nothing personal.”
