Looks like weather will be good this coming Sunday -
Every Sunday the Buddist Center of Dallas - aka Thai Temple has a Bazzar type food for sale by variety of their members or member restaurants.
This is not a restaurant but rather more similar to a Church type Bazzar
Tents with various vendors - Street Food
Food is extremely authentic, yummy and cheap :)
However PLEASE take cash since not all the vendors have POS type access.
There are limited tables and chairs so it would be good idea to have a portable chair in your car just in case.
The vendors are there til around 2:00pm - so don't worry if you can't make it before Noon, but warning - food selection is less at time passes :P
Also - bring your cameras - the Temple grounds/gardens are amazing.
