I went to this Sainsburys for the first time yesterday as I was in York city centre and needed some groceries. This is the only big supermarket in town that I know of (apart from M&S but they don't sell everything I wanted.) There is no big Asda/Tesco/Morrisons in town though.
It's a nice big Sainsburys and they sell everything I would need, lots of frozen food, fresh fruit and veg, tins, bakery, household cleaning, etc. It was busy when I went but they have lots of tills and self scanners so there was no queueing. read more
