Ask any local who makes the best meat pies and they'll tell you without hesitation, Dario's. Get in the line (which will probably wrap around the block) and choose from beef or chicken. They're also resold all over the country but it's best to buy them oven fresh at the source.
The fillings are piping hot – take care when biting through the crust. And Belizean pies are small, so grab a few.
