What I really love about Tate Britain is that it is out of the way from the high street; it’s small and cozy. I usually spend around 3 to 4 hours there. But it’s worth spending at least half a day there so you can get a good view of various exhibitions.
I went on a trip there with my daughter and was able to view the Henry Moore exhibition, which we were very much looking forward to. We were able to move around freely! This is mainly because we avoided the gallery during the peak tourist season.
