Plaza de San Diego is the square we walk across every day. It sits in the northern end of the walled city, small enough to cross in about thirty seconds, and it's one of the few plazas in the Centro Histórico where the whole point is sitting down and eating something. Historians will tell you it was a market square long before it was a dinner reservation. What you'll notice first is the tables: restaurants push them out under the trees, and from roughly 7pm onward the square is full and loud in the good way.
We're in San Diego, on Carrera 7, so this is our neighbourhood rather than a day trip for us. Here's how we'd actually use the square and the streets around it, in the order we'd do it.
One honest warning before you plan your evening around it: this is a place people eat outside, at close quarters, with music. If you want colonial hush, aim for the streets one block west instead.
