That One Westside “aquarium” shopping center in Sawtelle Japantown is really a hotbed of activity right now. I’ve recently told you about two new establishments moving in: Rok Matcha and Ding’s Noodles. And now two more are taking up residence. Window paper at 2202 Sawtelle Blvd is announcing the arrival of Paper Rice, a purveyor of Vietnamese spring rolls and bowls with two other locations. Just a few doors away at 2216 Sawtelle is the future home of Mollie Mollie, a new ice cream shop about which there is currently little information.
