I tried a small, signature iced black coffee from Starbucks, Gloria Jean's, Tim Hortons, & Dunkin'. My favorite iced coffee was from Dunkin' because the drink had a nice, refreshing taste.

I ordered iced black coffees from fast-food chains Wendy's, Burger King, and McDonald's. I wouldn't order iced coffee from Wendy's or Burger King again because I didn't like the flavor.
