There a couple of years ago and the main local drop is Fiji Bitter. Drinkable but unremarkable lager. Same for its low carb version Fjii Gold. You might find something more interesting at a resort or in Suva but I didnt!
Late seconding of @RichardLeahy's post. Fiji Bitter is unremarkable after the first few. Just don't expect a whole lot of other choices. Cocktails might need to be your saviour. Cheers!
