A delicious and charming restaurant situated just next to the Piazza Duomo, in the very center of L'Aquila. Be aware, however, that like many similar establishments they will not give you a written menu (there is one partly hidden near the door). Instead, the waiter will come to you and tell you very quickly and in Italian what dishes they have, and you will choose from that oral list. A complete meal (two dishes and a glass of wine) costs around 20 euro.
A very good low-budget restaurant situated near the Engineering department of the University of L'Aquila. It is a self-service and a complete meal (two dishes and tab-water) costs about 10 euro.
A delicious restaurant situated just next to the Fontana delle 99 Cannelle. This restaurant is slightly more expensive than the average, but of excellent quality.
