Kao Soi Gai at Nooch
Nooch (Paragon #B1-35, 6732-3313, with another location at Citylink) calls itself a "noodle bar" with a selection of Japanese, Thai, and local dishes. A lot of the dishes don't look that great, but I've always been a big fan of their kao soi gai. To be honest, I can't remember how this compared to the real deal that I had in Chiang Mai, but I do like the crispy noodles, oily chili pepper flakes on top (like the Cantonese stuff), and pickle/onion/lemon condiments here. I don't really ever veer from this at Nooch though - everything else here looks kinda nasty.
