Rodney Bay for me is not St. Lucia you could be anywhere there is nothing typically St. Lucian about it. I would recommend it for those missing the creature comforts of home such as pizza, KFC, Burger King etc. There are 2 malls, neither of them very exciting really. Warning, the JQ Mall advertises duty free shopping, however most of the shops there are not actually duty free so make sure u ask before you buy as you may not be getting the deal you think you are. If you want local food jump on a bus to Castries and go to the local market. The atmosphere is typically St. Lucian there is a wider range of choice (in regards to local cuisine) and a bus ride will not leave you out of pocket.
