Tucked away in a narrow lane near the waterfront, tile-walled La Plata is a humble, well-loved bodega that has served just four simple, perfect plates since launching back in 1945: pescadito frito (fried fish), butifarra (sausage), anchovies and tomato salad. Throw in the drinkable, affordable wines and vermouth, and you have the makings of a fine, popular tapas spot.
