I have always wondered:

Dairy Queen Brazier

Stores serve a normal fast-food menu featuring burgers, french fries, and processed fried chicken products in addition to frozen treats and hot dogs. Due to the protracted rollout of the Grill & Chill concept, Brazier restaurants have been allowed to sell certain products originally restricted to G&C, including GrillBurgers.

The name "Brazier" originated in 1957, when one of the company's franchisees worked to develop a food system that would work for all Dairy Queen restaurants. A brazier is a cooking device consisting of a charcoal or electric heating source over which food is grilled. The term "Brazier" was the result of a brainstorming session with the franchisee's advertising agency.

The "Brazier" name has been slowly phased out of signage and advertising since 1993, although it has not been removed from all existing signage. Since the early 2000's, new or renovated locations which are similar to Brazier restaurants in terms of size and menu selection, but have been updated with the current DQ logo and/or exterior, usually carry the name "DQ Restaurant", although the DQ website's Store Locator still lists the non-G&C stores as "Dairy Queen Brazier" and the smaller stores "Dairy Queen Ltd Brazier".
However, the DQ website still considers their burger and hot dog lines as "Brazier Foods", according to the History section of the DQ website and some FAQ listed topics in the DQ website.
