da Nerbone
This tavola calda (cafeteria) in the middle of the covered Mercato Centrale has been serving Florentines since 1872. Tasty primi and secondi are always available, as are bollitos (boiled beef sandwiches), but the cognoscenti come for the panino con il lampredotto (tripe sandwich)—best when it's prepared bagnato (with the bread quickly dipped in the tripe cooking liquid) and served slathered with green and/or spicier red sauce.
