For many years, the Chinese food scene in Rowland Heights has been dominated by Taiwanese cooking, with dozens and dozens of Taiwanese eateries all along Colima, Gale, Nogales, and the other streets of the area. However, the east San Gabriel Valley is too falling prey to the phenomenon of the west San Gabriel Valley with the rise of mainland Chinese cuisine. While this isn't exactly news even in the Rowland Heights-Industry-Hacienda Heights area, seeing a restaurant called Mr. Lamb opening up was a real slap in the face for me on this point. Though their website (www.mrlambcali.com) says they specialize in Northern and Southern Chinese cuisine (and also indicates they're new to the state, since Californians never refer to "Cali"), I think Mr. Lamb is better categorized as Western/Northwestern Chinese food. For one you walk in and see two tapestries on the wall picturing camels and a third depicting what I would describe as Chinese minarets. The menu includes sections for platters (e.g., chicken, water boiled fish, lamb) running from $16 to $26 and skewers. Menu items include beef goulash with potato, and many lamb and spicy items. I had the Xinjiang fried noodles with lamb, one of a handful of dishes with Xinjiang in the name, including Xinjiang fried noodle soup. Nice and chewy as expected. Mr. Lamb is at 17863 Colima Road.
