There's something about this street, probably the fact that it's pedestrianised, that makes it feel like holidays. It also has a solid range of bars (Cafe Kick), restaurants (Berber & Q) and cafes (Brill) so is a good option for all times of the day. They have a quality variety of street food vendors operatin during the day, and fairy lights help it to come alive at night
The AA is Britain's oldest school of architecture, but anyone can take advangte of the great work going on there. You can catch really interesting public lectures and free exhibitions throughout the year. There are also occasional installations and event launches, a bijoux cafe and brilliant bookshop. A great place to hang out with the builders of the future.
