re: Rome then Tuscany- places to eat

Rome is wonderful...Tuscany is fun, but it's rural and spread out. I'd take Rome over the countryside any day....so many wonderful things close together.

A branch of the famed food purveyor Castroni is at Via Nazionale, 71. It's a good place to buy food souvenirs--chocolate bars, hard candies, jellies, jams, tea, etc. Plus it has a small cafe where you can sit and rest while enjoying a spremuta (fresh squeezed OJ). Here's the Castroni website (though for a different location): LINK

You also will be in the general area of gelateria Fatamorgana, one of Rome's absolute best: https://www.gelateriafatamorgana.com/web/

If your travel plans include the Vatican/St Peter's, then I'd put Pizzarium on a must-eat list. Innovative, seasonally topped pizzas: LINK
