After a little more than three years in business, Bernal Heights brewpub and restaurant Old Bus Tavern is driving off into the sunset. 

In a message posted yesterday to the pub and restaurant's Instagram page, the owners made the announcement "with a heavy heart." 

"Unfortunately, like a lot of small businesses in San Francisco recently, the economic realities have caught up with us," the note reads. "Saturday, September 8 will be our last service." 

Owners Jimmy Simpson, John Zirinsky and Bennett Buchanan said that they have sold the tavern's lease to new owners, "who will carry on the tradition of providing the neighborhood with local beers and chill vibes." 

Via email, Zirinksy told Hoodline that while he's not able to disclose who the new owners are, "they will be making their own announcement in about a week." 

It's not clear if the "Old Bus Bus" — a 1971 VW bus used for outdoor parties, events and catering — will also be retired.

Until the spot's last day, the owners encourage folks to stop by for a "farewell bit or drink so we can extends a huge thanks and a hug." 

"We opened our doors ... with the goal of providing a warm and lively space for our neighbors and friends to congregate over a tasty beer and good music," the Instagram message continues. "On those terms, we feel that we succeeded."
