Dale. There’s a great joint called La Cueva del Mar. There are actually three. One in Guyanabo, one in Calle Loiza and another in Old San Juan. Great seafood, great drinks, great prices.
Dude...my first thought was, “Who is Dale, and why is he being invited?” Took me a moment to realize it was Dah-leh.
As to restaurants, I will defer to the locals, I may go every year, but I don’t stay long enough to really know the good local spots.
