I came here to actually pick up some of the No.7 hot sauce the owners sell alongside their existing cafe. I ended up going early on a Saturday morning so I thought I would give some of their Nutella inspired offerings a shot. I ended up having a Nutella Double Shot Espresso and I would say it was quite impressive. I expected the drink to have an overpowering flavour of Nutella but to my surprise, the drink had a nice balance of sweetness to espresso. Furthermore the drink wasn't heavy at all so I didn't have to feel too guilty at all LOL.
If you're ever in the area, definitely give this place a check!
P.S When you order any Nutella drink, you get to lick the remaining Nutella off the spoon. Something small, but it adds a nice novelty to the drink!
