Was this at a different location in the 80's

The first time I ate here was circa 94, and it was already an established predence on the Riverwalk.

No this is the original location.

Don't know, sorry, just passed through San Antonio.

I cannot speak to it being here in the 80's, but due to the modern style of the restaurant and the menu it is entirely different from anything that existed in the 80's.
