The Roman food philosophy is based on locally produced, environmentally friendly, fairly priced items. The idea is to buy locally pay a fair wage to the farmers, and sell for a reasonable price.
There are plenty of touristy overpriced food options in Rome but I suggest you do some research and look for a true Roman experience.
There are lots of wonderful restaurants & markets. I highly recommend Eataly (Piazzale 12 Ottobre 1492 Roma) for a fun grocery shopping experience and Hostaria I Clementini (via di S Giovanni in Laterano 106).
There is so much to love about this magical city and its local food and wine culture. Food is one of the things that bring me pleasure and cooking with the freshest possible items makes even the simplest of dishes unforgettable.
If you are a true foodie you can book a food tour.
