Hmm..well their website at www.villasdeguatemala.com not much help, other than what you said about the "local specialties"

That being said the picture of the "sample offerings" looks like they have a whole broiled "Mojarra" fish which is a local white fleshed fish from Rio Dulce (and very yummy!) served with a side of arroz y frijoles negros (rice and black beans). If they have it when you go, try it!

Perhaps travel cannot prevent bigotry, but by demonstrating that all peoples cry, laugh, eat, worry, and die, it can introduce the idea that if we try and understand each other, we may even become friends ~~M. Angelou~~
