Review: We ate at Aum several times the first week we were in Chiang Mai, as many of the guidebooks suggest it. Even though the food is wonderful, the staff leaves much to be desired. Our last time eating at Aum, an older manager type women sat at the table beside us and watched my partner and i eat, until she came over and asked us if i had any children. She explained that she thought we had kids, as I was so large (gesturing hugely with her arms). I would rather support a place with a more comfortable vibe and a little less sizism.
