Big, bar style ice cubes (SAT)
Where do i get them in San Antonio?
I don't know if you're looking for them in a bar, or for home use. However, if it's the later, you can order these ice cube trays on Amazon.com. I got some recently and am very happy with the large ice cubes.
In case the link changes in the future, the name of the product is Tovolo King Cube Extra Large Silicone Ice Cube Trays.
