The Paper Mill
Fantastic setting right by the canal. There is free parking, you need to just go to the bar and give your registration number. Highly recommend a hot chocolate by the canal in winter or during the summer an alfresco meal outside! It's a huge place so there's plenty of space inside if it's raining!
Excellent pub with interesting beers, freshly cooked food with open kitchen where you can see your food being prepared. Outdoor seating and balcony in upstairs restaurant. Less than 5 mins walk.
