I'll answer a couple of these,
Try Georges Kitchen for breakfast. They also do a good evening meal.If you catch fish have them prepare it for you for supper.Good and reasonable.
Do Jambel for sure. Great Jamacan/belize.
I recommend the Lamanai trip. We used Seaduced but i'll bet all are good.
You must do the Palapa Bar jam session on Sunday afternoon. North of the cut.
