Number Nine isn't necessarily the most "authentic" Vietnamese food you'll ever have, but it's yummy and quite veggie friendly. They offer vegetarian versions of both pho and bun, as well as vegetarian egg and spring rolls (vegans note, the egg rolls are not vegan). This is a slightly more upscale-feeling restaurant in Long Beach's hip retro row neighborhood, so it's a good spot for a date or a dinner out with friends. They also have a more-interesting-than-usual beer menu. Highly recommended.
