This is very cool. Jeffrey Orlick of Jeffrey Tastes is hosting the first leg of his 5-Boro Pizza Tour this Sunday (May 2) with a trip across Queens. There are still spaces available; contact Mr. Orlick if interested. A description of the tour:

We will tour for 5 Sundays, a different borough on each day. We will sample a slice or 2 from each shop, ordering by the pie. At the beginning of each tour, I will have a map of 5 remarkable pizzas of varying styles in the borough. Of those, only 1 will be from last year (The "winners" from last year). We will be transported by car. The drivers' food is paid for by the passengers. We order regular, no topping pies by the pie as the measure for comparison. You can order more, but keep it safe. This is a marathon, not a race. Attendance is in groups of 8s.

And just so you know you're not going on a half-ass tour, check out Mr. Orlick's recent pizza activity on his site; he's been prepping for this like a madman.
