Within the Cathedral, not in the coffee shop. In the disabled toilet and you get the key from the coffee shop (which is very good and has high chair). Bit cold in there and not that clean but handy location.
“Absolutely fantastic product that cools the formula VERY quickly. When you pour the boiling water in you really have to get the formula powder in as soon as possible because it starts working right away. When it says it takes a couple of minutes to cool I think that is how long it takes to cool a full flask.”
