There are a ridiculous amount of temples in Chiang Mai. I don’t think you can walk more than a block or two without stumbling onto a temple. It reminds a bit of Kyoto in that way.
The khao soi from Khao Soi Khun Yai was my third bowl in Chiang Mai, and it’s going to be very, very tough to beat.
The coconut pudding pancakes (or kanom krok) I just had are odd — tasty, but odd.
There’s a whole bevy of street vendors that pop up in the evening on a stretch of road across from the North Gate in Chiang Mai. There’s a lot of tasty food to be had here, but the most popular stall (by far) is Chang Phueak Pork Leg Rice.
