Well I'm sorry to say, I often want a quick bite so even something pedestrian like Pad Thai or Kee Mao is good.

Found a vegan restaurant in Chiang Mai. The food is terrific, first vegan restaurant I've ever been to and they have a varied menu. Meals for under 300 THB and they take credit cards and it's a roomy, air-conditioned dining room. They have a couple of tables outside but there are mopeds and cars whizzing by constantly, though it's walled off from the street, you can hear the traffic.

It's called Goodsouls Kitchen, kind of in the northwest corner of the Old City.
