seafood/restaurants are excellent.
Indeed the coast there is def better than, for example, Margate.
Without appearing to be in the pay of the Flanders tourist board, I can only concur with that.
I particularly like Koksijde Bad and Nieuwpoort. they are so much less tacky then their neighbours on our side of the channel / North Sea, and the pedestrianised promenade makes for very pleasant afternoons relaxing with a decent (if expensive) meal and some interesting beer.
How they go about attracting British tourists back in numbers I don't know.
