Worth a detour from sightseeing is this year-round, indoor market, whose offerings include pop-up marketers hawking their particular specialty, like small-batch pickles. At least 40 vendors set up in stalls or at counters selling fresh produce, flowers, cheeses, artworks—everything from olive oil to oysters. Stop by Salt & Sundry for lovely handcrafted gifts; visit Sundays at noon and join a yoga class. There’s always something popping up. Open Open Tuesday to Friday 11am to 8pm, Saturday and Sunday 8am to 8pm.
