Chipotle Mexican Grill is expanding its new ShopHouse Southeast Asian Kitchen concept, which launched with a single unit in late 2011 in Washington, D.C. The company opened one unit in Los Angeles in June and was on track to open two more in July — one in Santa Monica, Calif., and one in Washington, D.C.'s Georgetown neighborhood. The company also signed leases for two additional Los Angeles-area restaurants and two more in the D.C. area — all expected to be open by mid-2014.
