Meredith Smith is the editor of Slice, the pizza review blog of the Serious Eats network of food sites; in a post about the Knoxville pizza scene, she gives finds that's changed over the years:
"My view of the pizza landscape in Knoxville is dated. Growing up, it was the closest big city to home and I made plenty of trips there, but that was before the new standards set forth by the mid 2000s pizza renaissance. It remained, in my mind, a swath of the country populated by pizza buffets and the big chains. So it was with genuine surprise (and a touch of skepticism) that when passing through this holiday season, I saw all sorts of new-era pizza joints popping up on the restaurant maps."
The post includes a very positive review to Hard Knox Pizza: slice.seriouseats.com, Jan. 3, 2013.
