Not strictly a market, but a four-floor homage to Italian ingredients and cooking. Thirty different breads, 25 shelving bays of pasta, two aisles of olive oil... and you’re only just scratching the surface of what’s here under one roof. Browse the cookbooks, chocolate, local wines, and beer and cheese, or stop for a meal in one of the ingredient-themed restaurants and food bars (although prices are a little steep). Eataly is foodie heaven, and open daily from 10am until midnight. If you can’t make it to this main branch, there is a smaller Eataly located under the colonnades at Piazza della Repubblica (walking distance from Termini Station).
