I am noticing that there have been no recent reviews.... I personally think Acqua al 2 (2 is said, Due, its 2 in Italian) is authentic, its not to say that Old Spaghetti Factory isnt but what Acqua al 2 has to offer is a special meal that any self respecting Florentine would go out to eat at a favorite ristorante. Its not the lasagna that their mothers would slave all day for. Plus, the owners just opened a fashionable little wine bar called TOAST(like salute) enoteca e cucina (wine bar & kitchen). This place is so cool. So dont let the reviews sway you away, just relax and have a good time, trust me!
Pros: Assaggio di Primi, Fillet with Balsamic
Cons: Bad Reviews...
