Six days before leaving Boston

I went and had a bowl of pho by myself this afternoon. I've been trying to avoid eating too much Asian food before I leave but I couldn't get it out of my head, and it was that or watch daytime TV. I'm excited to compare what I feel is excellent pho here in Boston, to pho in both Ho Chi Minh City and Hanoi. I realize it will be different but I'm wondering how different it can be. Broth, noodles, various meats, various accompaniments. The ingredients always vary between restaurants, but there is something comfortingly consistent about this dish. Sometimes nothing can soothe you like a big bowl of pho that you know you wont finish.
