Irene, a bright and colorful restaurant at the Hotel Savoy, is great for lunch on the sunny bistro terrace outside or for a nightcap sipped on a velvet banquette at the bar inside. The kitchen turns out traditional Tuscan cuisine with surprising modern touches: The classic tomato-and-bread pappa al pomodoro comes stuffed inside ravioli, and the vitello tonnato (veal with tuna-caper sauce) is topped with ribbons of shaved fennel and served with the sauce on the side. On Sundays, the popular “Lunch at Nonna’s” menu is a loving nod to the restaurant’s namesake. Pre- or post-dinner, grab a seat on the terrace, overlooking Piazza della Repubblica, to enjoy wines served in retro-style carafes and bubbly poured into 1950s coupe glasses.
