You can’t miss Lillas Pastia, as this self-proclaimed House of Truffles is located on the ground floor of the historic Círculo Oscense, a superb example of local Modernist architecture.This elegant restaurant, which takes its name from one of the characters in Georges Bizet’s famous opera Carmen, has become one of Spain’s leading names for truffles, given that the Huesca black truffle has been increasing in popularity over many years. Here, chef Carmelo Bosque, who is also heavily involved in various cooking projects for those with learning disabilities (such as the Club Inclucina), offers cuisine with a contemporary slant based around seasonality and the use of the best native-grown ingredients.
