You might visit this charming South Grand spot for banh mi - it's in the name, after all - delicious sandwiches with thinly sliced meat, pickled vegetables and sometimes pté on a crusty baguette. Or you might decide to test the neon sign in the window that proclaims the best spring rolls in St. Louis. These, too, won't disappoint. Or you might just settle for a simple bowl of pho, redolent of cilantro and basil, or paper-thin char-grilled pork over rice sauced with nuoc cham that hits the perfect spot between sweet and spicy. Whatever you choose, husband-and-wife owners Thomas and Lynne Truong will make sure you leave their restaurant full and happy.
