If you're staying near San Pedro, Belize the chances are that you're going to find yourself at the world famous Palapa Bar. It's located 0.5 miles north of the San Pedro bridge, on a dock overlooking the ocean. The Palapa bar is an expensive yet fun place to eat, relax, and throw back a few drinks.
The burger there is pretty good too. Nothing fancy, just good meat, and your basic toppings. I had high hopes considering their BBQ is really tasty and I wasn't disappointed. For being outside of the US, it's a good burger and if I were living on the island, I could see myself ordering it again.
