Okonomiyaki village and Downtown Hiroshima

May I ask if the above two are the same places?
Thank you.

Downtown Hiroshima refers to the Downtown Area of the city; Okonomiyaki Village is just a building located within that area.

Does this mean Okonomiyaki Village is located at Downtown Hiroshima?
Is this Downtown Hiroshima located at Hondori, Naka Ward, Hiroshima?
Thanks.

Thanks William5.
I am likely to be lost in the Okonomiyaki Building.
Any recommended restaurant that offers something unique to Hiroshima?
Thanks.

Couldn't recommend any okonomiyaki place as we are not into it, but another "must-try" in Hiroshima is oyster. Besides a regular restaurant 2 interesting sites for oyster meal in Hiroshima are a river boat and a market-like self help grill place.

For oysters, I am thinking of kakiya in Miyajima.
Its set lunch is 2150Y which is pretty expensive. I wonder if it is really worth the money.

Oh, I am spoilt with choices. Which one is more value for money for oysters?
