Insiders' Tip!
Small, cheap looking thai restaurant that just opened a few weeks ago. No fancy decoration, just some pics of King Bhumibol on the walls. Only a few tables, and you're basically sitting in the kitchen. Badly marketed on so many levels, this place probably will still explode with customers soon enough.
The food is the best (authentic!) thai food you can get in Vienna, the service is great, and the other patrons are interesting people most of the time - the people who come here obviously come because of the great food.
Been here three times in just a little over a week, and i'm thrilled!
