This was both a dynamic and a trying year for the Peninsula dining scene. Palo Alto's Maum won its first Michelin star. Bacchus Management Group, perhaps the area's best-known restaurant group, added swanky Selby's to its family. International eateries opened or are on their way here, from Telefèric Barcelona to Singapore's Killiney Kopitiam.

Many restaurant owners, meanwhile, spoke out about struggling to keep their businesses afloat amid a tight labor market, high turnover and the increasing cost of doing business in the Bay Area. These pressures will continue to play out in 2020, with many in the industry worried about the future of the locally owned, middle-range neighborhood restaurant.

Read on for a roundup of noteworthy restaurant news of the year and the openings we're most looking forward to in 2020.

TEARFUL GOODBYES

We said goodbye this year to a handful of longtime eateries: The Prolific Oven (39 years) and Round Table Pizza in Palo Alto (52 years), Applewood Pizza in Menlo Park (36 years), Martin's West in Redwood City (10 years, Cho's Mandarin Dim Sum in Los Altos (39 years, including at the original Palo Alto location), and Mountain View's Tied House (31 years), which closed abruptly over the weekend, the owner said because of a need to remediate a chemical spill linked to a prior tenant's dry cleaning business.

While there's no singular reason for the closures, the owner of The Prolific Oven had some pertinent words for what customers can do to prevent family-run independent food businesses from becoming an endangered species: "It's in the power of the people where they choose to spend their money," said Regina Chan, whose parents Henry and Sophia Chan bought the bakery in 1996. "I hope that I'm wrong and that small businesses and family businesses can continue to thrive in the Bay Area, but it's going to be up to the consumers to really show that."

HAPPIEST REVIVALS

A happy counternarrative to all the closures was the revival of much-loved restaurants this year. Mike's Cafe gave Palo Alto's Midtown neighborhood its favorite restaurant back after a lengthy renovation. New owners renovated and rejuvenated the 167-year-old Alpine Inn, giving back to the Portola Valley community its favorite gathering place and watering hole (now, plus wines on tap and wood-fired pizza) for years to come. Su Hong Palo Alto closed, but a former waiter reopened it under a new name, keeping on the same chef and changing little on the menu. Rose International Market returned to Mountain View after a four-year development-induced hiatus. And in a holiday miracle for sandwich lovers everywhere, Woodside Deli reopened in Redwood City last week, with the owners of Colombo's Delicatessen in Pacifica, who are related to the original owners of the local deli, at the helm.

MOST EXPENSIVE BURGER

Selby's wanted to make a name for itself by serving "the coldest martini on the West Coast," but perhaps should have considered going with "the most expensive burger on the Peninsula." The swanky restaurant, located on the border of Redwood City and Atherton, drew attention for its $50 Black Label cheeseburger: a patty of dry-aged hanger steak, short rib and chuck, topped with black truffles and Époisses, a soft cheese from Burgundy.

A MICHELIN STAR FOR MAUM

The chefs at Maum, Palo Alto's high-end Korean restaurant, took home their first Michelin star in June, less than a year after opening. Co-chef Michael Kim said the accolade had been a "lifelong professional goal" for him and his wife and co-chef, Meichih, who draw on their Korean and Taiwanese roots at Maum, which means "heart and soul" in Korean. Fine dining continues to grow on the Midpeninsula, which is now home to six Michelin-starred restaurants, including Maum (Baumé, Protégé, The Village Pub, Chez TJ, Madera).

THE YEAR OF DELIVERY

In a sign of the times, DoorDash opened its first shared delivery kitchen in Redwood City in October. Under one roof, several food businesses -- Nation's Giant Hamburgers, Rooster & Rice, Humphrey Slocombe, The Halal Guys and Chick-fil-A -- can deliver throughout the Peninsula without having a brick-and-mortar restaurant here. The bright red, 6,000-square-foot building is emblematic of shifts and tensions in the dining industry, spurred by the growth of third-party delivery apps like DoorDash, Caviar, UberEats and others.

NATURAL WINE BOOM

The Peninsula got its first dedicated natural wine bar this year with Salvaje. The downtown Palo Alto bar (369 Lytton Ave.) defines natural wines as those made organically on biodynamic farms with minimal intervention and little to no sulfates or other additives. (Salvaje appropriately means "wild" in Spanish.) The small, cozy Spanish-style building Salvaje occupies feels like having a drink in your friend's living room, and the intimate setting is ideal for peppering the helpful staff and owners with questions if you're unfamiliar with natural wines.

MOST ANTICIPATED OPENINGS OF 2020

Early 2020 will see the local debut of two ambitious, modern Indian restaurants with connections to San Francisco: Ettan (518 Bryant St., Palo Alto) and Rooh (473 University Ave., Palo Alto). The former will be led by Srijith Gopinathan, a native of southern India and executive chef at the Michelin-starred Campton Place Restaurant in San Francisco. The latter is a new outpost of a popular San Francisco restaurant of the same name, but with a unique focus on open-fire cooking.

In Mountain View, beer drinkers and pretzel lovers are still not-so-patiently waiting for the much-delayed arrival of Ludwig's German Table (383 Castro St.), which will likely materialize next year. Owner Ben Bate spoke out this year about the costly setbacks he's faced in the city permitting process.
