LARGE grocery store?? The GOURMET Marche in Simpson Bay is closed, yes. I never really considered it a large grocery store. The Market Garden is the large grocery store in Simpson Bay and it is open. They have higher prices than most other places though.
Market Garden prices are a bit higher, but we really like the convenience of having a store so close to where we stay. I also believe their produce is fresher than that at the Grand Marche. Some of their produce is grown on the island at the Rasta farm.
