My wife and I have visited a couple of sites on or near Plaza de la Merced in Malaga: the Picasso Museum and the Picasso Birthplace Museum (which I have reviewed separately). the square is lovely, spacious and surrounded by eateries and tapas bars. I would like to recommend a tapas bar, La Esquina de la Merced (which isn't yet listed separately in TripAdvisor). We had four tapas - boquerones en vinagre, potato salad, serrano ham, and cheese, with two beers, one large (jarra) and one small, followed by two espresso coffees (a single and a double). Everything was fine: the boquerones were very tasty, the serrano ham was perfect, and the tapas were just the right size (even the potato salad!). The bill came to just over 10 Euros. Highly recommended!
