Get there early, it lines up quick!
This is definitely no secret anymore. You have to be looking for it, but more people know about it these days than not. The pizza slices are pretty fresh and a good size, however they are not out of the ordinary. I can get this same style pizza, similar flavors, same price and quality in San Diego at over a dozen places.
I would go again, as long as the line is not too long. Its a good spot to check out for sure, however I don't know that it really lives up to the hype. Its typical.
