One of my favorite things about being in London was wandering around at night. All of the lights make it look extra beautiful and even when there are a lot of people around, it somehow still seems peaceful. We spent a lot of nights walking around the Leicester Square area, which turned into our go-to spot for getting food after a night out (specifically a noodle stand called Wok To Wok and a place next door with really good falafel). We also made a bit of a habit out of getting ice cream at Haagen-Dazs even when it was cold outside.
We also spent a good amount of time on Oxford Street & Carnaby Street, both of which have amazing shopping that I didn't quite take enough advantage of. We ate at a couple restaurants in that area as well - Wagamama and Spaghetti House - and I would definitely recommend both. These photos are from all of the places I just mentioned as well as a couple from Chinatown, which we randomly wandered over to one night and I thought the decorations were really nice.
