Restaurant on Playa Larga

Every man for himself. But for my dollar go to El Caguamo. At the T make a right and go down about 5 restaurants. LLLLLAAAAAAARRRRRRGGGGGEEEEE pool by the entrance. Roberto and his wife Ene are the proprietors with the biggest smiles on the beach. Lupe is the waiter and his wife does the cooking along with Roberto. Seafood fresh, awesome portions and great prices. A cool breeze along with the warm seas. BE THERE. Great mezcal also.

We like Popeyes, turn left at the T, maybe the 4th place down. Haven't tried Oleaje or El Caguamo, but we will.
As far as pools are concerned, most of the ones at Playa Larga seem to be intended for the kids - and on the few days that any of Larga's restaurants are busy, you wouldn't want to share the pools with the kids.
That said, in addition to a kid's pool at the restaurant, Popeyes also has a large pool across the road.
Another choice, albeit a longer drive from Zihua, is Restaurant Lagartos on Playa Blanca. Nice little pool, terrific food and, important to us, none of the pounding hip-hop crap that sometimes can spoil an afternoon at Larga.
