I'm going to Phila for flower show and Dad wants to take us out for dinner. He's loathe to traipse into the city from the 'burbs, and has his eye on William Penn Inn in Gwynedd. Is that a good choice? I'm more an adventurous eater than my old man, but is the cooking at least good there, or should we consider somewhere else in northern burbs? Oh how I wish he'd go for Susanna Foo. . . . Or White Dog.
