Tacos in PV beyond Centro?

We're heading back to Puerto Vallarta in January and want to explore beyond the 5 de diciembre/centro neighbourhood where we usually stay. We've been coming to PV for about a decade now and have found some great taco carts and hole-in-the-wall places for chilaquiles, birria, and al pastor tacos, but we haven't ventured very far north of there. Any recommendations for tacos and other great eats in other parts of town?
