Pho -- that beef-broth-and-rice-noodle soup that's the most ubiquitous offering in Vietnamese cuisine -- is always eaten for breakfast. It's always eaten for lunch, too, and dinner on the streets of Da Nang, and as a midnight snack by drunken scooter kids in Saigon trying to sober up for the long ride home. But as a breakfast dish, pho is unsurpassed, and no one in town does it better than Pho 79. With one broth and a million different combinations of meats, herbs, spices and noodles, breakfast at Pho 79 can be a never-ending journey through the flavors of the Far East. But by nine in the morning, the Aurora outlet, at least, can be so packed full of hungry neighbors coming from the Japanese-Korean-Viet-Thai neighborhoods surrounding Havana Street that there's no space left for the casual culinary tourists.
