Right in the heart of Old San is the Cortes brothers chocolate restaurant - not just desserts, but a whole menu full of items that contain chocolate.
And wow was it good!! Everything I ate was delicious! You're in for a real treat - I recommend the chocolate grilled cheese for sure.
You'll find more than chocolate at Casa Cortés ChocoBar—it's a full restaurant created by a longtime Puerto Rican chocolate maker, with an upstairs art gallery where the owner's family collection is displayed. But the menu does indeed focus on chocolate, revealing the many ways it can be incorporated into dishes both sweet and savory, from chocolate waffles to chicken in chocolate butter sauce. There’s also a heady selection of hot and cold chocolate drinks and cocktails.
