One can recommend The Mango Tree - Check out the Chef’s Specials (tastebud joys) on the daily board - but do book early for that very desirable front row table overlooking the Pitons.
BIL & SIL took a Buffet lunch at The View as part of a private tour a few years ago, which they enjoyed with a distance view of The Pitons
I will invite @reedprincess to suggest alternatives for consideration, being excellent for both food and views.
Enjoy checking out the Websites, the photos, the Menus and the ambiance in making a selection, but with a big note to self, do book early for a prime view table.
