The pizza was pretty good, the dough and mozzarella are made fresh. They use many high quality ingredients. It's a journey, not a destination. However, you can probably make equivalent pizza at home.
Watch out, people line up 3 hours in advance to get a table! There's a reason that the bar in the house next door is open for business before the restaurant is. If you're in line 3 houses down the sidewalk, you have a good chance of waiting 2 additional hours to eat.
