I went to Viet Huong in Chinatown (727 N Broadway, Suite 107, (213) 626-0764). It's a friendly, comfortably cramped place with about eight tables and a multicultural clientele in the Far East Plaza mini-mall, next to Mandarin Deli. They have two menus, one with just text and the other with pictures. I ordered the vermicelli soup with pork sausage, pork balls, and chicken. I ordered it partly because the pork sausage looked so interesting in the photos. It came with a plate of bean sprouts, a lime, and some leaves whose identity I cannot recall. Although I basically liked the soup and the place, it wasn't entirely what I'd hoped, e.g., there wasn't any pork sausage in the soup and the chicken was rubbery. Also, I think I didn't do a good job of stirring the leaves etc into the soup -- I will try to improve my technique next time. I also ordered a soda chanh, Vietnamese carbonated limeade, and that was quite good.
Outside the restaurant there are some tables where genially pushy Vietnamese grandmothers try to sell you various Vietnamese foodstuffs. After some deliberations, I got a small styrofoam tray of sticky rice with enough purple food coloring for a truckful of lab rats. Compared to Vietnamese sticky rice I've had in the past, especially in Orange County, I'm afraid that this version was disappointing as well. It was way too sticky -- impossible to eat without a fork, which wasn't provided -- and way too sweet, to where I couldn't finish it.
