Theres endless stuff for a vacationer to do in New York City, but I once joined a graffiti tour through SoHo and the Lower East Side that proved to be one of the coolest opportunities of my trip. The guide showed us work by locals and internationals in spots wed probably never think to look, and verbally tussled with pissed-off pedestrians (our group was large) to boot! Since last July, Seattles most famous neighborhood has offered daily a similarly insider-y adventure via Angela Shens Savor Seattle tours at Pike Place Market. Theyre two-hour trips through the stalls, where youll munch on favorites like piroshky, smoked salmon, and fresh produce while spying secret spots and hearing the history of vendors and Market characters. Sundays are low-stress Singles Mingle days, in which Shen promises locals will be surprised by what theyve overlooked. Including, maybe, a hot dish of another kind.
