Mendocino Farms has big plans for Houston. Known for its decadent sandwich, the California-based restaurant has already announced that it will open two Houston-area locations in Rice Village and Uptown Park, but it isn't stopping there.

Downtown office workers will get their chance to try the restaurant, too, courtesy of a location in the 48-story 609 Main at Texas office tower, real estate developer Hines announced. The approximately 3,600-square-foot restaurant will open this fall. Mendocino Farms will join Prelude Coffee & Tea, a coffee shop and cafe from the owners of Blacksmith and Morningstar.

“We are thrilled with the opportunity to join one of the best office locations in Houston," co-founder Mario Del Pero said in a statement. "We look forward to launching a great project at 609 Main at Texas.”

The Los Angeles-based restaurant is known for its luxurious sandwiches like the pork belly banh mi and the hot Italian that pair high-quality ingredients with freshly baked breads and vegetables sourced from local farms. Those sandwiches, along with some entree-sized salads, have made the restaurant a hit. Backed by investment money from Whole Foods, the company has grown to over 25 locations in Northern and Southern California.

Once a culinary wasteland — save for Treebeards — downtown's central business district is starting to emerge as a legitimate dining destination thanks to the opening of Finn Hall and the plans to open the Understory food hall later this year. With Shake Shack and Mendocino Farms also revealing their intent to open downtown, the days of being compelled to suffer sad tunnel lunches may be drawing to a close.
