Come on, a crappy sandwich with that tasteless laotian white bread can't really be declared good food. I eat better every lunch when I grab a decent sandwhich here, not to mention when going to a random restaurant.
But my own ranking:
1. Laab in any form
2. Yam in any form
3. Som Tam & Kaow Niaow
4. Gaeng Kiew Wan (don't know how to spell it)
5. Tom Yam
