One salutary effect of Spain’s fiscal crisis has been the proliferation of inexpensive restaurants with menus from upmarket chefs. This welcoming, breezy spot in the Grand Hotel Central is the brainchild of rock star chef Ramón Freixa. In contrast to his fine-dining restaurants (where he has four Michelin stars), Avalon feels like a casual American spot with Catalan food. It’s bright and unfussy, and offers free Wi-Fi. The dishes are unfussy as well—a dozen little plates ranging from mini-pizzas to green salads and small rice plates, and then nine larger plates: three different burgers topped with fried egg, three different roasted sausage casseroles, three different canneloni. It’s playful and very affordable.
