Foodwise I'm sorted for all other days during my forthcoming 5-day trip but just noticed when looking at my itinerary that I've nothing booked for the main day of the La Merce Festival. What can I expect? Will locals all eat out for lunch and will restaurants be exceptionally busy? I suppose it makes sense to book somewhere in advance but am not quite sure where? Looking for Catalan/Spanish/Mediterranean cuisine. Am solo traveller so needs to be a cosy, inviting place where I'd be comfortable. Don't want to spend more than €25-30. Any ideas?
