Have been to John Dough's several times now and will be heading back -- Pizza has always been very good as are the salad bowls. Love the family style servings! The only issue I have is that each time we've ordered the same salad, it's been different. Sometimes it'll have just iceberg lettuce and the other times it will be mixed greens. Note to JD's- stick to the mixed green lettuce...so much better!
Last time I was here, the service wasn't very good, which was disappointing since the place was pretty empty. Our waitress disappeared after the food was delivered, didn't clear salad & plates (which would have been fine if they weren't crowding the table), and didn't stop back until it was time to bring the check. It wouldn't keep us from going back, though...
John Dough's is a solid addition to the SoNo area. For one, it's completely unpretentious unlike a lot of the other places. And two - it's totally affordable (and has some great beer selections).
The pizza is comparable to New Haven style. It's not nearly in the same league as Modern or Pepe's, but for the Norwalk area, it's solid competition for some of the best slices around. If you live here, you should definitely check it out at least once, and try it for yourself!
