'Gusto is an institution in Rome. In the city center off Via del Corso
on Piazza Augusto Imperatore behind the Ara Pacis museum.
A huge building divided into a restaurant, pizzeria, wine bar, bookshop, wine store, osteria, and a coffeeshop.
I really love the wine bar for an aperitivo, Italian-style. You buy a glass of wine or a cocktail and get finger food from a rich buffet for free, the best in Rome, I'd say with delicious mouth-watering food!
The que is long everyday, so I recommend you come here early. It's a bit pricey, but in the end it's worth the wait and euros spent. http://www.gusto.it/
