Del Taco serves fresh brewed Gold Peak iced tea, not to be confused with the Gold Peak tea from concentrate. When brewed well, fresh brewed Gold Peak iced tea has a really good taste, but like many other fast food restaurants at Del Taco it is not always brewed well.  Jack in the Box, Carl’s Jr. and Blaze Pizza are two other well known chains that serve fresh brewed Gold Peak tea. The price is usually similar to other fast food restaurants, around $2.50 for a large.  And refills are self serve at most locations.
