Being lactose intolerant can really cramp your style amung Boston's ice cream fanatics. I read about the wonderful flavors- in ice cream, but are they out there in yogurt or soy? PLEASE tell me where to find them!!!
Both Toscanini's and Christina's have various yoghurt flavors, usually a (small) subset of what's available in ice cream. They also have sorbets which, at least for Tosca's, can be phenomenal (mmm mango sorbet).
