You really don't know what you're missing!.
I have been going to Margherita's pizza for over 20 years. It is out of my way now, but I will still drive to Jamaica Avenue to get a slice or two. People raved about Gaby's and I finally tried it. Gaby's is good, but Margherita's is exceptional and I have to say is the best in the city. The slices are pricey for the neighborhood (and always has been), but the fact that it is always packed attests to the value. I highly recommend it!!!!!
