A downtown outpost of the John’s Island OG, this sunny all-day cafe and market beckons customers to grab a breakfast sandwich and coffee to go or linger over, say, mustard and tarragon chicken salad on a croissant and a mango smoothie spiked with ginger and tumeric. Come 3 p.m., the menu shifts to suppertime snacks like toast topped with smoked trout with dill crème fraîche.
