Food hall expands a winning formula.

The Market is in the midst of an ambitious expansion that will increase the Market Street grocery store and food hall's space by 50 percent while doubling - maybe even tripling - the number of food vendors. Though partner Chris Foley is staying mum on specifics, he teases that eight to 15 new tenants will feature ramen, Korean food and burgers, and there might even be a vegan deli. When they open, the newcomers will join the lineup of poke, pizza, a juice bar, Blue Bottle Coffee and organic fried chicken sandwiches at the San Francisco site. [ABSTRACT FROM PUBLISHER]
