It's hard not to get excited (and hungry) when you listen to Irene Li talk about Mei Mei, the restaurant she co-owns with her brother Andrew and her sister, Margaret. I got a real “joy hit” as she explained the siblings’ commitment to using sustainable, locally-sourced food and treating employees fairly. Irene was generous to talk with me some more about how she and her sibs are changing the way Bostonians think about the food we eat and who is making it.
