I have worked at the Olive Garden since 1997...it's now 2006...and we have NEVER in my 9 years of service there had a "secret" recipe for our raspberry iced tea, nor do we get it from nestea...(which you CAN buy on shelves)...all we do is brew our LIPTON iced tea...and add our raspberry syrup...same as any other syrup. Add it according to taste.
