The Opera House, Tunbridge Wells

I am not fond of JD Weatherspoons but visited The Opera House because of the fact it was an opera house turned pub.
You get to eat on stage and appreciate the views of the seating on the balcony and the opera house surroundings.

As well as The opera house, The Counting House used to be owned by the Bank of Scotland where you can eat in the vault!
The Chief Justice of the Common Pleas has a cell while you can dine in a church at The West Kirk, Ayr.
