This is 3 floors of food heaven - various restaurants and coffee bars all serving Interesting food and there would definitely be something for everyone.
It's a bit off the beaten track - about 10 minutes walk from Pyramid metro station, but well worth the visit - especially if you are staying in the Testaccio area.
The store is a bit like a gigantic version of Selfridges food hall and if you're self catering and have a car would be a fabulous stop on the way into Rome.
We just had breakfast today - cappuccino and chocolate cornetto (croissant), but would love to come back and sample the rotisserie chicken, it looked delicious.
The cookery school on the top floor was fab and we'd love one of these in the UK.

Big shopping mall/grocery store.
Various restaurants serve burger, fish dishes and other delicious things. 3 levels and open daily until midnight.

Eataly is not a typical restaurant as tourists would expect, but it serves some of the best Italian dishes one could find in Rome. I have been to “Carne” a few times, where they serve both beef and fish, and to a couple of their other restaurants. My friends and I always enjoy the food, beer and wine. What we have a problem with every time is the service. While the kitchen endeavors to provide their best recipes, there’s something between it and the customer’s table that does not work right and needs to be fixed by the management - the waiters. Their approach towards clients is far from being appropriate. Some of the reasons are the following: some hot dishes are served at low temperature. Hitting them up takes a long time, and by the time they return to the table it’s dessert time. If a group orders different dishes, they are prepared in a different timing, and they are served as they are finished, which means that 2 or more people around a table are likely not to have their dishes at the same time, and some may eat cold food, or just eat alone while others will wait for their orders. If you order a starter (antipasto), it will not necessarily be served before your main course. Unspeakably, it may be server together with the main course, or even more disturbing, after your main course is served. Sitting can also be an issue. Once, when we arrived, most tables were free, we chose one, but the waiter, despite our insistence, refused to let us sit where we wanted. Attracting the attention of a waiter is not obvious. If they are not serving your table they hardly come to check if you’re fine. Paying the bill is not easy either. Last time we felt like standing up and departing, as there was no one around to bring us the bill. There’s a clear need of proper training. I hope the management takes action to bring the waiters to similar level as the kitchen staff, and I’ll be looking forward to an appropriate service next time I return to Carne.

Such a great selection of high quality Italian food ranging from breakfast to dinner. The shop itself has an amazing selection of treats to take home. We came here on multiple nights as it was near to our hotel near Tremini station. Highly recommend especially for English tourists!

If you like Italian food, then Eataly is the place for you. Enjoyed the pizza and a wonderful wine, then was able to purchase treats for myself as well as every kind of food souvenir you could want. The building is GIANT and contains little restaurants, each with a specialty! So many grocery choices too, like pastas, candy, wine, breads....This is easy to access on the Metro from Termini. Disembark at Piramide and walk through the underground concourses and there you are at Eataly. Worth a trip for anyone with free time in Rome.
