I don't necessarily think of that spot as up and coming, but I do like that section of Mission. There are a lot of really great restaurants there such as Blue Plate, Mi Lindu Peru, the Front Porch (which was featured on Check, Please Bay Area), Zocalo, Emy's Spaghetti Shack, and Good Frikin Chicken just to name a few. There is also the Safeway right there which has just recently had a facelift. Oh yeah, and we can't forget Mitchel's Ice Cream right there on Guerrero! You are close to public transportation, and have easy access to three great neighborhoods: Inner Mission, Bernal Heights, and Noe Valley. I think it's a great spot.
