It’s been a year since Besito Mexican has taken over the old Roots Bistro Gourmand spot at 399 Montauk Highway.

And in traditional Mexican fashion, the authentic eatery is having a fiesta to celebrate its anniversary.

“We couldn’t have imagined that the welcome to the South Shore would have been as amazing as it was,” said the restaurant’s owner, John Tunney III. “Then to continue that excitement the entire year is more than we could have asked for.”

Besito Mexican, which has two other locations on Long Island, is celebrating in West Islip this weekend, Sept. 29 and Sept. 30.

On both dates, between noon and 4 p.m., Besito is offering guests 2-for-1 specialty margaritas, a complimentary street taco per person, and free tequila tastings.

“Our new family and friends on the South Shore have made our Besito family even more extraordinary and we look forward serving our friends on the South Shore for many, many more years to come!” said Tunney.
