Pho Phong Luu keeps its attention on the details that make a bowl of Vietnamese noodle soup memorable: clear, fragrant broth simmered for hours, fresh herbs, properly cooked noodles, and meat prepared with care. The family-style restaurant also serves bánh mì and other comforting specialties, but pho remains the reason Austin diners repeatedly send newcomers here. Portions and prices encourage an unfussy meal rather than a special-occasion production.
