A couple weeks ago, Mulberry Street Pizzeria at 1655 E. Thousand Oaks Boulevard in Thousand Oaks changed ownership and became Butler's Pizza, a family-owned pizza parlor. I called them (same phone number as before 805.379.1121). Visit their Facebook page at www.facebook.com/Butlers-Pizza-1388453068128799.
Mulberry Street originally opened at this location in April 2013, about a month after the previous occupant, PizzaSalad, closed its doors after five years in business.
Thanks to Alison F for the heads up!
