Went to both these places yesterday.
Joe's: Personally, I don't understand the hype. Arrived at the corner location, finding a wait of a few ppl. Line went quickly, and I had my slice in a couple minutes. The crust was VERY thin, and when folded, cracked not only at the actual crust, but also in the middle of the pizza (i.e. I was holding half a folded pizza, half an unfolded slice). This is unacceptable to me. Sauce to me was non-descript, and cheese was also basic.
Bleecker Street Pizza: Tried their Nonna Maria. Great fusion between the basil, the parmesan reggiano, the sauce and the fresh mozz. Would have been quite enjoyable but for the undercrust of the pie. I admit, I don't get the bread crumbs. It adds a very pronounced texture that overwhelms the other ingredients. Personally, for a nice added flavor, I far prefer corn-meal, which when done right complements rather than overwhelms. Perhaps, it's more of an acquired taste that takes a few visits to fully appreciate. I'll be back.
