Following a £45 million development, the renovation has transformed the Grade II Millbank building at the gallery.
The renovation includes a new spiral staircase in the centre of the atrium, a members' cafe and bar in the circular balcony and the reopening of the Rex Whistler restaurant on the lower floor.
There is also a new Archive Gallery, for which different contributors will select items solely from Tate's archives to create a temporary display.
The renovation looks fabulous and is truly worth a visit.
