Am currently staying in Grand Luxxe in Nuevo Vallarta, Mexico. I am happy to report that some of the restaurants on the property are serving delicious food, some more than others. First night ate at Samba outside near the Grand Mayan: expensive and not at all good. However, dinner at the Seafood Market Punta Arena was quite fresh and flavorful: wonderful shrimp, lobster etc for about $50 pp including tip.
The Del Lago buffet is better than ever (for 255 Mexican pesos pp) with wonderful complex Mexican dishes, fresh green juice, freshly made in front of you empanadas including Huitlacoche and more conventional stuffings, etc. Can't recall all the options but the food is high quality, plentiful, and interesting.
Restaurants outside the grounds so far: Eddies: best chile relleno stuffed with shrimp, not so great snapper with mango sauce.
Tacos el muelle: good Mexican combination plate with chicken mole, empanadas and tacos for two for 150 Mex pesos.
