There is a link in the first paragraph to the most recent Top 50 list in 2017. That is still linked to on the TM site, but apparently they’ve taken this one down.
I notice the Top 50 list has notations of businesses that have closed but this ‘interim’list does not. If you’re planning on making a road trip, I’d check in advance.
Blood Brothers BBQ in Houston, on the shorter list, has announced plans to open in Las Vegas next year.
