Even if you aren't staying at Blancenaux, I recommend a trip there to visit. You need your own car to do this, and it requires a bumpy drive over unpaved roads for about nine miles. We went in the afternoon and had time to walk around the facility and sit beside the river. They seemed pretty open to this, just no jumping in the hot tub (which is the most gorgeous setting I've ever seen for a hot tub). There is a nice bar and deck area, open all day, which had nice tropical beverages.
The dinner location is way romantic. There is an indoor area that has a lodge atmosphere and then an outdoor covered porch that feels like it's in the forest.
The size of the waitstaff was someone overwhelming; we counted three people checking on us during dinner, so we were confused about who to ask for things.
Dinner consists of standard pizzas, which are supposed to be the specialty, and other dishes ranging from Belizean food to steak. One highlight was the bread with oil and balsamic vinegar, which was not your standard oil and vinegar--I almost licked the plate. The pizza was great, but not quite spectacular. The crust was perfect, and the sauce was a little plain for my taste, but with fresh-tasting toppings like mushrooms and artichoke hearts. Their Coppola wine went well with the pizza.
But dessert was definitely their specialty. There were only two options, but the torte we had melted in my mouth and had a lovely presentation, as well. A perfect ending.
