Seafood takeout by the Pantheon
A new seafood take out shop will open just a few steps from the Pantheon. It is Street Fish, the new offering of the chef of the nearby seafood Trattoria La Rosetta. It will be offering seafood and fish sandwiches on "rosetta," a round roll for about €10. Street Fish will open July 3 and close August 11 for vacation (of course). It will reopen in September.
It is not on Google maps yet, but from the description, I think it will be next to L'Antica Salumeria and across the piazza from the Albergo del Senato.
Here is the article describing it:
