£2.79Diet Coke 500ml
£8.59+Furious ChickenAbout This Dish
The Subway Diet Coke 500ml costs £2.79 and carries 2 kcal. It is the other zero calorie cola, with a distinctly different flavour from Zero.
On flavour it is lighter and sharper than Coca-Cola Zero, which is a genuine difference not a marketing one. Subway publishes calories for it but not a full nutrition panel, so the other figures are left blank on this page rather than estimated.
It works best the calorie free cola for people who grew up on it.
None on the numbers. Diet Coke and Zero are the same calories and different drinks.
Every alternative in this part of the menu is listed with its own price and calories, which is the quickest way to see where this one sits rather than taking a single figure on its own.
Prices here are collection prices from a reference UK store and refresh whenever the site rebuilds. Subway UK branches are franchises that set their own, so treat the figure as a close guide rather than a promise.

That depends on the exact product and, where it is made to order, on your choices. Check the Subway allergen guide or ask in store before ordering.
