Chinatown Tour Foodies are like homing pigeons — they head straight for the culinary heart. When Martha hears her food-loving friends are coming for a visit, she calls Trish for suggestions on what to do with them. Trish's first thought? A Chinatown tour. Trish asks one of her chef friends, Greg Couillard, to lead the merry band as they make their way through the stalls, booths and shops of a teeming Chinatown.
