I'm a new poster and I really enjoy this site!
As I was reading about the great Kimchi place in the posting about the Fresh Pond area, I was reminded how lucky I am to live in the Davis Square/Porter Square area. (Redbones, Gargoyles, Formaggios, Tu Y Yo, etc.) But I've never seen anyone mention Pemberton's Garden Market in Cambridge for groceries.
The store is on Mass Ave, between Porter Square and the Arlington town Line (an easy walk from the Davis Sq T). It used to be just for gardening supplies, but then they added a food area which is WONDERFUL. I no longer buy ANY produce at the regular grocery because I get it all at Pemberton's, where it is fresher, cheaper and with a great organic selection. They also have a beautiful deli and bakery area, great cheese, and overpriced packaged stuff (along the same line as Formaggio's). Their produce beats any other place I've been (including that place that draws huge crowds in Lexington, Wilson Farms). They sometimes have really unusual selections, like odd fruits and vegetables that they just happen to find. I love that. But most of all I love their prices.
