I really couldn't tell you which pub is the best. There are at least three pubs around Reeth village green so just take your pick. The 17th century Black Bull with its up side down pub sign draws the crowds (it was supposedly put like that by mistake but it was allowed to stay like it and has become a signature of sorts) with its free house assortment, outside tables and popular pub lunches. The landlord really wants the house to look "more Yorkshire than Cumbria", exactly like it did when it was built but nope, the facade has to stay whitewashed as a public house like this cannot be altered at all now it is in a national park - at least that's the court case so far so there is always that to discuss here.
We stopped for a pint in the Inglenook bar in the King's Arms pub, also in the Green and also a free house. We had a very cosy time by its huge fireplace and with great windows overlooking life outside. It also has music evenings and serves food. Several of the pubs has bed and breakfast too.
Straight from Brymor Ice Cream parlour near Jervaulx Abbey and Wensleydale, this is as local an ice cream as you will have in the Dales and very nice it is too. I am in love with the rhubarb crumble but there are loads of other flavours.
