A recent thread asking about the worst local spin off had me thinking about what are the best. I know there are plenty of Boston chefs and restaurateurs who have expanded their business successfully (from a Hounds perspective not just a financial perspective) and I'd be interested in hearing what you all think. One that comes to mind immediately for me is No. 9 and then B&G (although it does seem like Butcher Shop might be an outlier for Barbara Lynch?). Others?
