Tapas bar La Tasca in Liverpool was named the chain's restaurant of the year at its annual awards ceremony last week.
The awards ceremony followed the annual La Tasca conference, which gave an opportunity for managers to share best practice ideas.
Liverpool branch manager Javier Mellado received a three-day all expenses paid trip to Barcelona, courtesy of Estrella Damm.
"The managers and their teams have all shown immense dedication to their businesses and intuitive understanding of what their customers want," said
La Tasca managing director Andrew Buchanan.
"The standard has been outstanding this year and all categories were highly competitive so I congratulate all our managers who were nominated."
La Tasca is part of the Bay Restaurant Group, formerly operating under the Laurel banner.
