People remember bad speeches, bad dresses and bad food. When you hear about a function or event these are statistically, the most common things people are going to mention. To an extent they are the points of difference by which events are distinguished. Of course there are other factors, but really nailing your event catering is a sure way into peoples memories because food is just so personal and universal.
I started using The Food Agency a few years back and as much as the food, I just love having them at my events. The staff are all really helpful and cheery and the food is so tasty and beautifully presented that it makes me look like I really care about details. I use The Food Agency, because I do.
