We've been to both, and we prefer the Old Town Scottsdale Grimaldi (our Roadfood.com review) to the Brooklyn Grimaldi (Michael Stern's Roadfood.com review). Heresy, perhaps, but tasting is proof (that's a Scottsdale pie pictured above). At least it is for us. Sandy Ikeda did a comparison of the two for The New York Sun, and while she gave a slight edge to the hometown favorite, she was surprised at how good the Scottsdale pizza is. She thought the crisp and smoky crust tipped it in favor of Brooklyn. We think just the reverse, that the crust is crisper and smokier in Scottsdale. Another excuse to try them both again...
