There was a time in the recent past where Burger King served some type horrible tasting instant iced tea (it may have been either Nestea or Lipton Brisk). They have since switched to fresh brewed iced tea which definitely an upgrade and is pretty decent tasting. It doesn’t taste quite as good as McDonald’s and from my experience is as inconsistent as other fast food restaurants. If you are going to pay more than $1, I would venture to Chipotle, In-N-Out, or Panera Bread for far superior fresh brewed iced tea.
