Saigon Noodle Bar

This colorful, hipster-friendly Vietnamese-Argentine eatery is a cozy and casual – and affordable! – foodie haven in Retiro. Order spicy noodles or pho at the counter, plus craft beer or wine by the glass or carafe, and watch the world go by through the big glass windows. There's a second location (with extended hours) at Mercado de San Telmo.
