Welcome to Eater Tastings, where Eater SF editor Allie Pape shares the best restaurant and bar news of the week.

SAN FRANCISCO—Everyone loves a $1 oyster deal. Here are 15 places in SF to score bivalves for a song.

BAY AREA—The Eater Heatmap gets its October update, with lots of white-hot new fall openings to try.

MILL VALLEY—We sat down with the gents at Mill Valley Beerworks to discuss their first year as a full-fledged restaurant...and got the scoop on their forthcoming 20-barrel Presidio brewery.

NORTH BEACH—Isaac Shumway, bar manager of Tosca Cafe, shared the scoop on the cocktails he'll be serving when the much-anticipated historic space re-opens under new owners next week.

CASTRO—As Spanish spot Canela turns two this week, it's scored some brand-new (and very swanky) decor, plus revamped menus. Take a look at both.

RUSSIAN HILL—Acquerello called out one of their patrons on Twitter for wearing Google Glass to a $100-plus tasting-menu dinner. Glassholes, leave the specs at home, okay?

TENDERNOB—Star chef and Liholiho Yacht Club pop-up king Ravi Kapur has finally settled down two years after departing Prospect, taking the exec chef gig at a still-unnamed restaurant owned by the team behind Nopa and Nopalito.

LOWER POLK—Bitters, Bock & Rye is about to open its huge restaurant spinoff, with lots of BBQ and house-brewed beer.
