A few months back, I went to The London Aquarium, which was an interesting and good day out.
Without going into too much detail, they have almost all types of fish from around the world, in many different water types.
There is also a huge shark tank ( I forget the species name now .. ) and myself and the girl lucky enough to catch the feeding time .. amazing experience.
We also got to feel some ( human friendly ) stingrays. The bird had already felt one as she recently visited Florida and had the experience of touching a stingray, but it was my first time and they are funny little characters !!
I ended up buying a £9.50 memento stingray in the shop at the end as a memento !! Sad or what !!
Anyway, comes recommended for fellow Brits or potential tourists.
Brilliant day out.
