Just got an email this morning telling me that all Bite Card holders (which is free) can get a free bottle of water with the purchase of any sandwich, burger, panini, mezzalunas and filled rolls from any of the listed shops on the card (In rail stations).
The best thing about the offer is that you can still use the 20% discount too so you get 20% discount on your food and a free bottle of water!
If you don't already have a Bite Card - get one
or order one directly:
Click the link to print the voucher and see all the details!
Some of the reastraunts included in the deals are:
A Piece of Cake
Camden Food Co
The Pasty Shop
Great deal if you ask me!
