As someone who has been trying a lot of Vietnamese restaurant in North America, I would say that Saigon Noodle's Pho is relatively comparable to all other good restaurants out there, and certainly the best in Madison.I've had better ones, thus the four stars but I still come and eat here often whenever I crave for a hot, delicious pho.
I always get the one with everything in it (no. 19?) but if you are a beginner, I would suggest trying the pho with some beef steak (ask them to make it well done), flank steak, or the meatball.
Not a pho fan? You can always come here for the rice or rice-noodle dishes (my fave is the one with grilled chicken and spring roll). Not feeling hungry enough? Try to super yummy Viet spring rolls with peanut sauce (non-fried, with shrimp and beef slices inside).
