Messy means good eating. That’s what Shayna Seymour learned in Cambridge at a Harvard Square noodle shop, Santouka. A Brookline restaurant known for its Middle Eastern cuisine is putting its falafel on a food truck and taking it on the road, while a legendary donut maker is bringing its creations to the Financial District (who wants a dowich?). Plus, Shayna discovers unusual bagel flavors in Cambridge, and a guided wine tour in Boston. And, because we’re still hungry, we check out a burger spot and a French bakery.
