"I must say that the first comment on this thread was really surprising to read. Not only are the Hummingbird Bakery cakes the best I've had in London, but the one thing that always sticks out to me, whether I order over the phone or in store, is the customer service. It's a shame, but in most retail establishments these days the staff seem to be disinterested and bored, however at Hummingbird I am always greeted with a smile, served quickly and sufficiently and the staff really know their stuff. They also up-sell in a brilliant way, none of this obvious money grabbing sales you get elsewhere, but they really take into account what you want and need.
I work in events and most themes are fashion or beauty, so I often order large amounts of the Hummingbird cupcakes for the events - usually at the last minute (isn't that how everyone works?!) and each time I have gone back to Hummingbird as they have always executed my requests in a professional, happy and sufficient way. I have ordered the same amount as the first commenter and never had any problems whatsoever. They seem happy to be serving 1 cupcake or 100 - I don't think the size of the order is an issue at all.
I'm really glad Hummingbird are in this category as to me, they really are the best cupcakes (and service) around. I need a red velvet now..."
