Any ideas where to find them? if available here in chiang mai. Specifically Sour Cream & Onion ones.

Not sure about sour cream & onion, but there's Bake & Bite that's generally well liked, especially by Americans.

(It's near Duang Tawan intersection on Chang Klan Road, just south of the intersection of Chang Klan (NIght Bazar) and Sridonchai road on the left hand side, when coming from the Night Bazar.)

Or the Bagel Cafe, behind the Irish Pub.

Bake and Bite and Art Cafe have onion bagels with cream cheese which is what you probably mean.

Smoothie Blues on Nimmanhemin Rd. also have onion bagels. But be warned, all these places have approximations of bagels but after 3 years I've yet to find a real bagel in Chiang Mai. Philadelphia cream cheese is readily available at the supermarkets though.

I was never that big on bagels, but they taste as good as the ones in San Francisco, which is good enough for me.
