This is the best place for gelato in Madrid. It is a bit off the beaten path for tourists, but is…read moreright next to MadridRío, so it's a nice place to stop on a hot day while walking through the park. It can be busy on the weekends. It doesn't close during the siesta AND is open all day Sunday - which is definitely a bonus.
They have a wider variety of flavors of gelato in summer months than in winter, but they are open year-round. There are three different sizes for one flavor, two flavors, or three. I usually got the two flavors and I thought it was plenty. That one only cost 2,90 euro. They don't skimp, they really scoop a lot on the cone. If you aren't into cones, you can get a cup.
They also have different types of coffee with and without gelato as well as with or without liqueur. There are milkshakes and gelato covered waffles available as well.
Excellent value for the price!
