A Debate House was a type of establishment found in many Vulcan cities and other settlements. Debate houses were described as combination coffee shops and public forums where ordinary Vulcan citizens met to debate issues that they considered important.

In 2165 Phlox, Tobin Dax, and the Cardassian exile Iloja of Prim made several visits to a debate house in the city of ShiKahr. While there they listened to Vulcans such as T'Zhae and Soreth debate the Kir'Shara and the Syrrannite Reformation. Impressed by T'Zhae's words, Phlox passed them on to Jonathan Archer, who used them in a speech to the Vulcan people after the V'Las coup had been defeated.
