The best pho downtown if you can get a seat!
Easily my favorite pho restaurant downtown that also has some good vermicelli dishes. The only issue is that a lot of people downtown feel this way. You will need to be there before noon if you want to be sure to be out of there before one. I also enjoy their salad rolls which are pretty typical. There are three sizes (S, L, XL). I usually eat a large and then remember I only really needed a small so I would recommend starting with that size unless you're really hungry (or plan on taking some home). Service isn't great as they have a small staff with a lot of patrons and the owner/manager doesn't place any emphasis on courtesy but he doesn't need to due to the quantity of patrons.
See you there at lunch (although I think they're open at other times).
