Where to take someone for a business lunch in Perth?

[200bhp]

I have to entertain an important supplier from Italy on Friday, we've got a few meetings booked for the morning and nothing from noon onwards. I'm thinking about taking him to Frasers for lunch as it has that nice touristy view of the city - Anywhere else that I should be considering?

He's in his late 40's and is booked in for knee surgery when he gets back to Italy so cant walk too far or
