Lo del Diego is a shop that leans into the cheese (unironically) with all things Diego Maradona. Enter and you'll be confronted with a life size statue of D10S running right at you. Behind him (above the registers) is a recreation of Boca's Bombonera stadium. It's cheesy but hey, if you love Maradona it's a must visit for a photo or to pick up one of the idol's jerseys.
There is a cafe inside as well, but if you're going to grab a coffee in this area I'd head to the Caminito and enjoy your coffee with the tango performers instead.
