Yes, Pete, Wetherspoons is now open. It doesn't yet seem to have made a big impact on local beer prices, though the amount of business it is doing must be affecting the local licenced trade.
Don't expect prices there to reflect W's prices elsewhere. We are told that their method is to survey local prices, then adjust downwards a bit, and that the resulting price here is their second highest in the country. Course that may just be a folk tale, but they are certainly not cheap, just cheaper than most local prices.
