After arriving in Laos we had a great dinner.
Vietnamese was our least favorite food thus far, although almost everything was pretty good. Everything was very fresh in Vietnam, even to a fault. There seems to be a southwest-to-east gradient in southeast Asia; with the best and most spicy in Thailand and the mildest in Vietnam.
Other notes about the Vietnamese food:
Not enough ice in shakes;
Some Jasmine tea, and very good, but rare; nothing like the ubiquity of tea in Japan;
Our favorites involved fresh spring rolls with some cooked fish or tofu inside;
The coffee was both the best and on occasion, the worst so far, but usually fresh. Not nearly so much instant coffee;
Do as the Indian guys we met do-bring your own bag of spice!
