Diners at CHAYA Downtown can dive into a shellfish-centric menu for its inaugural month-long “Crustacean Food Fair.” The LA Beat was invited to a tasting and recommends it highly. The dishes are also reasonably priced for such fresh, upscale seafood. Rock Shrimp and Bay Scallop Ceviche with Aji-Amarillo Ponzu ($14) has just the right balance of acidity without being overbearing. Pan Roasted Langoustine Ojja with Rock Shrimp, Scallops, Clams, Mussels, Eggs, and Chorizo ($29) resembles a paella with a richer sauce. Blue Crab Pilaf and Tai Snapper wasone of my favorite dishes, the fish cooked to perfection. The Half Maine Lobster & Jidori Chicken Hot Pot with Porcini Mushrooms, Cippolini Onions, Baby Carrots, and Heirloom Potatoes ($36) is on the higher end, but can be split between two people easily and four with either some good manners or fighting. The special menu continues through Sunday, October 28.
