Fantastic displays and a good souvenir shop too

Visited Osaka with a group, and personally all of us found the aquarium to be the best thing to do in Osaka.It is one of the largest aquariums by the bay side and has fantastic large glass displays. Some of the displays such as the seals, penguins and dolphins drew a lot of oohs and aahs from the crowd.The central large tank houses a whale shark, hammerheads, sting rays and what not.Takes easily 1. 5-2 hours to finish the visit and they have food & drink for sale as well.The souvenir shop also was quite nice and most of us bought something for memories.
