I actually think McDs is pretty decent, but I do prefer DD.

I've never had McDonalds regular hot coffee, so I can only comment on their iced coffee. It tasted like something with coffee flavoring added, as opposed to coffee. According to their website, this is what's in their vanilla iced coffee :icon14:

Premium Roast Coffee. Light Cream: Milk, cream, sodium phosphate, sodium polyphosphate, DATEM, sodium stearoyl lactylate, tetra sodium pyrophosphate, sodium hexametaphosphate, sodium citrate, carrageenan. CONTAINS: MILK. Vanilla Syrup: Sugar, water, fructose, natural (plant source) and artificial flavor, caramel color (with sulfites), potassium sorbate (preservative), citric acid, malic acid. Ice.

You left out "various bodily fluids from disgruntled employees."

:icon18:

Seemed so obvious it went without saying.

I'd have to ask an employee with more than half a brain to find out what exactly is in their iced coffee. Whenever I see them making it, it looks like its all cream and no milk and nowhere near enough coffee, which also appears to be from an espresso machine. It's mroe like some kind of messed up iced latte than actual iced coffee.
