New dining options

Flurry of activity around Rittenhouse Square. Mix, the brick-oven pizzeria, coffee shop and salad bar at 2101 Chestnut St., opened Wednesday (9/17). Melograno's relocation into 2012 Sansom St. should be ready to roll Friday (9/19) after a plumbing snafu. El Fuego's long-delayed second spot at 2104 Chestnut St. (across from Mix) is up for Monday (9/22).
