Ok. I won't even begin to attempt to defend my 4 year old position on Dewey's, but being that I'm about to become the mayor of this place on foursquare it's safe to say I've had an attitude adjustment.
I've really come around to their regular red sauce pizza. In fact, as of the last 12 months, it's probably my most preferred pizza in the area. The fact that the pies aren't dripping with grease plays a big part in the appeal. Also, some of their monthly specials are really fantastic (hello mexican pizza!).
I still maintain the Green Lantern is just not ok, but it's clear to me that there are plenty of people that disagree with me on that point. I'd recommend Sarah Z's opinion that you should go with white sauce instead of red sauce. Red sauce + Pesto is the part I couldn't wrap my head or tastebuds around.
Anyway, now that I'm a regular here, I'm still amazed at how consistent Dewey's is in their exceptional service.
