Honeygrow, the Philadelphia stir-fry and salads chain a restaurant analyst once said had the ambiance of a Penn sorority,  has drawn another $6 million from its investors, bringing total private capital raised by the chain above $70 million, which cofounder David Robkin points out is among the highest recent Philly-area venture totals for a non-health venture.

Honeygrow plans 15 new stores next year, Robkin says.

More on the capital-raising in this Nov. 10 filing with the Securities and Exchange Commission.

The chain's director-investors include Destination Maternity founder and former president Rebecca Matthias, cable-TV heir and hotel developer Brook Lenfest, and private-equity and real estate investors H. Scott Miller and Clayton Parrett of Miller Investment Management, along with Honeygrow founders Justin Rosenberg and Robkin.

Honeygrow operates a total of 25 stores in the Philadelphia area, smaller clusters in New York and Washington, and in Boston, Chicago and Pittsburgh. The company is also rolling out smaller "Minigrow" stores.
