Smith said: “The Spring Inn was in desperate need of love and attention, and I hope that with the new menu and refurbishment it will now achieve its full potential. The George at Wraysbury has achieved incredible success in just 12 months and my vision is that The Spring Inn will replicate at and quickly become a firm favourite with locals and a visitors alike.”
