While in San Francisco on our anniversary trip in May, we finally got to try a double-double with grilled onions. I have to agree with Joe H. ("The 5,000 Mile Burger") - this was the best fast-food burger I have ever tasted. As we don't get to California on a regular basis (last time was maybe 20 years ago), we despaired of having another any time soon. But I checked their website and found several in Arizona, one of our somewhat more frequent destinations. Now I know what our first stop will be every time we land in Phoenix.
So thanks to all who steered us to our first In-N-Out. It will definitely not be the last!
