When Cyrano suggests you "have an eye that sees well," make use of it to discover Bergerac down to the last detail. Take the Cloître des Récollets for example, a wonderful 16th century structure.

And don't forget those lanes you can wander along with your nose in the clouds to not miss out on any architectural details.
If he tells you, "If you had some letters and wit..." then quick! Head for the town's 2 museums (Tabac & Costi), and perfect your knowledge of the history of tobacco and Costi, the Greek sculptor.
If Cyrano were to ask you, "Oh! Do you only think about food?" You'd very likely answer, "Heavens yes, here gastronomy reigns! For that matter, I am leaving now to enjoy some treats and taste the delicious wines of Bergerac-Duras at Quai Cyrano."
