If you're talking about the Carrefour which used to be called the Grand Marche, by Mark's, it is MUCH larger than the Maho market. I don't particularly care for the Maho market, as the parking is so tight, and we do a LOT of cooking, so their selection isn't really what I would want. However, it is convenient to Beachside, so we do go there once a twice a week for quick stuff like the Daily Herald or a bottle of wine, although I find the prices at Maho market for wine to be very high, compared to Carrefour or Super U. I still very much miss the Gourmet Grand Marche which was in Simpson Bay.
