Zest was a great find. It is a bit off the beaten path, as the San Juan Water and Beach Club is in a nook in Isla Verde on the beach. We got there after sunset, but I suspect that sunset would be rather pretty, right on the water.
The food was well executed and had unique takes on Latin/PR traditional foods for many of the things on the menu, but also had some completely special treats. Everything everyone ordered was delicious and well executed.
Even if you are not a truffle fan, I highly recommend the truffle popcorn soup in particular. Also, the drink list has some really unique cocktails. Lastly, the wine list is very reasonably priced while having good options too. This is definitely a restaurant I'd recommend if someone found themselves in the area.
