I go to Thixendale at least twice a month, and yes there is about fourserious hills to climb out of the place, two I have now finally conquered after many months trying and two I have never ever attempted yet. But there is two other roads out of the village which are easy. But in the whole area there are other serious hills too but as the approach would be from York it would be uncharted territory for me so I do not know what else lurks in that area.
As for the pub and the cafe they are still there and I believe open but I never stop, soon as I start descending down into Thixendale its time to start thinking of climbing out the place.
As for OS maps prior to getting my GPS I used the following site for all my OS maps and just printed out what I wanted to whatever scale or detail I needed and throw them away when finished:-

Going into Thixendale from any of the 4 roads which come from the Southern side are steep decending into the village, and to get out the two roads that head West and East from the Northern side are easy enough but very scenic.
A quick look on mapsource with the Topo map shows that all roads approaching the wolds from the West have a serious climb up into the wolds unless I have missed one. Heading up towards Malton though and then heading South into the wolds seems less hilly.
