If Jamaica Plain is Boston’s Brooklyn, Amory Street is its Williamsburg — home to artists, hipsters, musicians, and cafes. The newest addition is bright, airy Cafe Bartlett Square, at the corner of Amory and Green streets, in an area known as Bartlett Square, the kind of neighborhood hangout where tattooed customers tote laptops and toddlers in approximately equal numbers. “Boy, is it exciting!” enthuses operating partner Phil Peterson, who helped open Hi-Rise Bread Co. in Cambridge years ago. Peterson’s vision for Bartlett Square involves “good solid food, nothing too fancy, using honest ingredients and good techniques.” The menu offers gooey grilled cheese and tomato sandwiches, a delicious Americanized banh mi, salads, soups, ice cream from Christina’s in Cambridge, the requisite froyo, and, perhaps the biggest draw, baked goods made by Peterson’s wife, Tania. She’s a pastry chef who has worked for caterers around town and appeared on Season One of Bravo’s “Top Chef: Just Desserts.” A “gourmand” cookie features oatmeal, browned butter, and chocolate chunks, striking just the right balance between earthy and indulgent; a fragrant, rich lemon-ginger scone packs in more ginger than seems possible. No wonder the place is buzzing. It would be welcome in any neighborhood. Cafe Bartlett Square, 154 Green St., Jamaica Plain, 617-524-5373.
