Photo or at the very least something requiring a fork—lunch is the way to go. Loads of restaurants knock down prices to as little as €5 for a plate of pasta, and around €6 or €7 for meat and fish dishes.
Fiaschetteria-Trattoria Mario (Via Rosina, 2r. Tel. 055218550) is only open for lunch. Go early and be prepared to eat on your feet—or squeeze in at the first available seat with groups of hungry locals.
On the other side of town, at Trattoria Accadi (Via Borgo Pinti, 56r. Tel. 0552478410; see above), a Japanese head chef turns out some darn good Tuscan Italian specialties at rock bottom prices. You can actually have two hefty courses for around €12 total.
Who said you can’t eat cheap in this most touristed of cities?
