Leave Grand Anse heading towards the airport. Keep on the main road, dont turn towards the airport but turn right at the next roundabout towards lance aux pines. 500m later turn right into a road called dusty highway (no sign of course.) then 100m on the right is a tyre and tuck repair place.
Above that is Rosies Cafe, the Grenadian equivalent of a truck stop or workers cafe. Its nothing to look at apart from being very clean, and its only open 10 till 4 BUT
They serve truly wonderful grenadian food. The best pig tail oil down or pork with rice and peas i have had anywhere. And with a fresh local juice it costs about 3-4 dollars a head. Give it a try for lunch, you'll be the only tourist there, till the news gets out... I have a relative working in construction on the new sandals there (which is another story) buu thats how i got to find it.
