Merci is one of my optional stops on my visits to the JTM.  It's a great place to stop in to pick up some basic food items to round out my shopping trip, like a bag of unbleached all-purpose flour, some olives, or even spices.  It's pretty tiny though, and I am constantly impressed by how many different items they manage to cram into the space.  Need some tempeh?  They've got choice!  Need some super fancy chocolate chips for your next baking adventure?  They've got you covered.  The staff are always pleasant and helpful and it's just overall a great place to have nearby to all the plentiful produce of the JTM.
