Via della Vigna Vecchia, 40r
An extremely popular restaurant due to its inexpensive but high quality menu. American study abroad students are frequent diners here but Select Italy clients have raved about the food, too. The favorites are "Assaggi di Primi" a sampler of five different pastas (a meal in itself) and the balsamic steak. The Acqua al 2 formula has proved so successful, that they've opened branches in San Diego, Ca. and Washington D.C. too. In Florence, it stays open till 1 a.m. so you can eat and drink into the wee hours. Serves dinner only; reservations recommended.
