If you ever are at the St Maarten airport (SXM), check out this food truck Johney Burger which is outside the departures area. They also have a location inside the airport.
They have a French Side and Dutch Side. You might say we went "Double Dutch" since we had the Phillipsburg (named after the Dutch capital) and the SXM (named after the airport which is on the Dutch side).
Phillipsburg is your basic bacon burger. The SXM had bacon with the addition of a grilled plantain which added some nice sweetness to the smokey bacon. Both cooked perfectly medium rare. And they both have Sunset sauce. Like most burger places, the ingredients of their sauces are a "secret" but I am guessing it is mayo, ketchup and sweet pickle brine mixed together. Maybe a little hot sauce for some kick. And both also had lettuce on the bottom so that the burger didn't make the bottom bun soggy.
Pretty good deal as well. Two large burgers (both with a huge portion of crispy fries), two beers and two waters was $41USD.
