ONCE A DIVE, NOW IT’S MISSION ROCK RESORT

Embracing guests in his signature bear hug, restaurateur Peter Osborne welcomed 400 last week to his latest venture near Mission Bay with a booming, “Welcome to the resort.”

It inspired many chuckles, as the old Mission Rock restaurant, now dubbed Mission Rock Resort, was a far cry from that tony description.

Osborne, whose Golden Bear Restaurant Group includes MoMo’s, Pete’s Tavern and Pedro’s Cantina, described the beloved dive’s seven-month $2 million rehab as neither a redo nor an updo but a “total makeover.”

“My biggest challenge was my patience,” Osborne said with a laugh. “But I’m incredibly lucky: I got great support from the port, and we’re part of this exciting neighborhood which includes Potrero, Mission Bay and Dogpatch.”

Retaining a maritime vibe and framed with expansive decks, the space sparkles as brightly as the bay through its wall of windows. The daily, sustainable kitchen serves a surf-centric menu with an oyster bar, as well as turf-centric bar-and-grill fare. But the hottest ticket may be scoring a deck seat to sip a sangria-style Pearry Francois cocktail. Construction king Larry

Nibbi fondly recalled when he and his business partners hired Osborne to manage Fior d’Italia, the North Beach restaurant they once owned.

Having honed his technique, Osborne upgraded to owner when he purchased the old Washbag from the late Ed Moose. By the late ’90s, Osbourne noticed the city scene shifting South of the Slot.

“After the Giants’ new stadium was approved, Pete asked for my advice

about a new place on King Street,” Nibbi recalled. “I said, ‘Pete, the ballpark’s not open for another nine months. What’ll you do?’ ”

But there wasn’t much else there, either. MoMo’s was the only go-to gourmet spot around.

“Pete didn’t listen to me,” said Nibbi with a hearty laugh. “And the rest is history.”

“Peep” show: When designer Ken Fulk was invited in May to create a travel window for the La Cienega design celebration, he crafted a sylvan setting dear to his heart: the historic dune shacks of Provincetown, one of America’s oldest art colonies.

Last week that replica, replete with sand and seashells, occupied his SoMa studio where Fulk celebrated his exhibition, “A Peep at P-Town.”

This one-night-only pop-up party, possibly the

largest gathering of PTown artists and their work in one place, also featured a Prohibition-era vibe with cocktails, canapes and a jaunty jump band. Lining the walls were mixed-media works on display (and for sale) by Provincetown artists such as filmmaker John Waters, Larry Collins, Jack Pierson, Mischa Richter and Michael Stuetz.

“This is my love letter to Provincetown,” said Fulk, who owns a home there with his partner, Kurt

Wootton. “Actually PTown is a bit like San Francisco. If you didn’t have to work, you could ride your bike all day — and there were no hills.”
