Note that the 53 C. Luisa address is production facility rather than a typical storefront. Their main storefront is in the mall of San Juan, but I wasn't able to get there during my trip. I called ahead to the production facility, and they were happy to accommodate my order there. They also sometimes accept orders via Ubereats.
The production facility building on Calle Luisa is unassuming and you will need to call to be let in. Once inside, they explained their available flavors to me, allowed me to sample some chocolates (which were fantastic) and let me choose the flavors in my order. A 16-pc box and a 9-pc box were about $119, which is on-par with the cost of other high-end chocolates.
I highly recommend the arroz con dulce flavor. It's unique and flavorful without being too sweet. read more
