Any Ital/Vegan food you get will be great. Seriously mouthwatering natural goodness (and no salt). Before I lived in JA, i didn't realize how easy it is and fantastic it is to be vegan there. Not a fan of Negril at all(or mo bay or ochi), but you will find some really decent food there.
Trying to remember where I ate when I was there.. Ras Rody's (a bit more $$ than used to-soup is very watery/diluted but this is Negril.., Royal Kitchen..). Basically if you are a bit lost, talk to Rastas (not on the beach-usually not really RastafarI in Negril-but can be hard to distinguish), and they will guide you..
edit: you can even go to juicy patty (a patty chain), and get soy (minced soy) or veggie patties. they are inexpensive and droolicious!
Thank you so much for the info! I think Royal Kitchen was the one I had heard of. Will definitely check out Ros Rody's too. Would most patty places have a vegan option? Or is that exclusive to that chain?
