If you find yourself needing to eat on the go (as I do far more often that I would like), and you find yourself in Tribeca (or Soho or the Upper West side- see below for exact locations), the flatbreads at GranDaisy Bakery are great.
My go-to is the Pizza Zucchini, which is served on a thin-crust flatbread with gruyere cheese. Their Pizza Cauliflower, also made with gruyere cheese, and Pizza Pomodoro, which, with nothing but tomato sauce, is as perfectly simple as it gets, are also favorites. For something different, I go for the Pizza Sciacchiata, whose sweet Champagne Grapes and Anise compliment the salty crust really nicely.
One makes a great snack, and two a fine lunch. For eating on the go, GranDaisy Bakery is one of the best bets I’ve found for something relatively light, not too unhealthy, and always supremely delicious.
