^^ The Tube is the best way to get around. I could do it by myself when I was a little kid. From Gatwick to London bridge is kinda pricey if I remember.... Anyways just stick to the trains , black cabs and other taxis are wayyyy to exspensive.
Also check out Greenwich , some pretty good curry resturants around there. And if you want some cheaper and a fun atmosphere , Pizza Express has good pizza lol!
