No mate, The Windmill is a left over sign from a previous business.
I actually though the Windmill was from the business downstairs, (a predecessor to Kava)
I have been in the Emperor many times.... (including Friday night) The value is unbeatable.
Even the lager is £2.80.
Might not sound cheap, but its a good 30 to 40p cheaper than the Queen Vic, The 147 or The Fountains.
