The Bay Area's second Shake Shack opens Wednesday in Larkspur, following the burger chain's much-hyped NorCal debut in Palo Alto last December.

The new fast food joint is planted in Marin Country Mart, at 1401 Larkspur Landing, an outdoor mall with plenty of trendy restaurants to hold you over while you brave the inevitable line for a Shackburger with cheese fries.

The Marin restaurant was built with crowds in mind — the restaurant is just under 3,000 square feet with multiple decks for dining, Eater SF reports.

The menu is also decked out with Bay Area sensibilities in mind, including the Golden State Double, a Richards Grassfed Beef double cheddar burger topped with pickles and smoked garlic aioli.

According to Eater, Shake Shack also whipped up two unique "concretes" (frozen custards, in the chain's lingo): Larks-brr, with vanilla custard, marshmallow sauce and crispy pieces and Mount Tam Graham, with dark chocolate chunks from San Francisco-based Dandelion Chocolate, graham crackers, marshmallow sauce and chocolate custard.

To sweeten the deal, five percent of sales from the Pie Oh My concrete (vanilla custard with a slice of pie) will be donated to La Cocina, a San Francisco nonprofit that helps food entrepreneurs — primarily women from immigrant communities and people of color — grow their businesses.

Shake Shack, Marin Country Mart, 1401 Larkspur Landing; Sunday through Thursday, 11 a.m. to 10 p.m.; Friday and Saturday, 11 a.m. to 11 p.m.
