It’s no secret that most Chinese restaurants actually have two menus: one with Americanized staples a la crab Rangoon; the other with funky offal-filled stews catering to Chinese predilections. At Taste of Sichuan, a sprawling Beaverton restaurant dedicated to the throbbing spices of Southwest China’s Sichuan region, the veil is lifted, with a not-so-secret “Wild Side” menu offering some adventurous flavors and authentic bites for American audiences. On this side of the aisle, strands of sour & spicy jellyfish, chunks of stir-fried frog jumping with pickled chili peppers and pork stomach strips are the norm.
