PHO. I love it so much.
When you're traveling it's the perfect meal. You get all full and warm like you're at home snuggled up.
Even though you get full - it's not the fat and nasty kind of full...like hamburger full.
When you're sick it's basically chicken noodle soup...only better. (Hung over counts as sick in my book.)
It's cheap. Wicked cheap.
The restaurants that serve pho are normally the kind of place where being solo doesn't feel awkward.
You always have leftovers.
