Cafe de Bangkok's chefs re-create homestyle Thai dishes on a menu blossoming with fragrant herbs and spices fresh to order. Aromas of lemongrass rise from Cafe de Bangkok Tom Yum noodles, whose spicy broth mingles the textures of ground pork and seafood with crisp bean sprouts and tender rice noodles ($11.89). Nimble hands prepare thick, marinated Bangkok pork chops with garlic and mushrooms before splashing the dish with house-blended soy sauce ($12.89), and spice ruby-red coconut curries with eight different spices ($9.89). Thai basil dominates plates of jasmine rice festooned with bell peppers, tomatoes, and medallions of meat in the basil rice wok ($9.89), whereas the peanut prevails over chicken and broccoli rama ($9.89) by blanketing their contours in rich sauce before fitting them with monocles and top hats.
