If you take the Tourist Bus, get off at the Sarrià stop. This neighbourhood, like Gracia, was an independent municipality before being annexed by Barcelona, though its pedestrian streets and traditional shops continue to give it a village "feel". Heading down its main drag Major de Sarrià, you'll come to the famous Bar Tomás (Carrer Major de Sarriá 49), which has the best "patatas bravas" in the city (12:00 to 16:00 and 18:00 to 22:00. Closed Wednesdays. Reservations not necessary). Getting there on public transportation is a little tricky: In the Plaça Catalunya station, take the S55 railway line (Plaça Catalunya / Sarrià) and after 7 stops, get off at the Sarrià station (you can use your T-10 ticket).
