Same for me,
in Chiang Mai Hom Coffee on the moat (Moonmuang) does a very nice hot latte for 30bht, you can sit outside and watch the people pass by, coffee extra hot.
Then out in the jungle is 129 Coffee, when I'm out cycling early I can watch the cows walk by, but the coffee is tepid rather than hot (Latte 40bht).
Then there's LakeView Cafe, set in a public park next to MaeJo golf course (Latte 50bht), lake and mountain views and a jogging track around the lake, coffee is hot.
