We can,'t get to the mother church, but can stop in Allston on route to catching our flight at Logan. Is the pizza too inferior to justify stopping in Allston?
Not only is the taste vastly inferior, they use different ingredients. My DH has a soy allergy and can happily eat the North End version but the Allston version made him really sick.
Depending on where you are coming from, Max & Leo's just off Exit 17 in Newton is superb coal-fired pizza and it's easy to get back on the highway to get to Logan.
The Medford Regina's is pretty good, worth eating in my book.
Nothing compares to the original oven, though.
