It's fine but constantly plagued by poor stock or weird stocking decisions.
For example, chicken breasts. Single people are going to want two chicken breasts. They're almost never available in that size because too few are stocked in the fridge. So you can get four or eight instead -- if you want to have to throw them away because you're not eating for a family.
Other products get listed and delisted seemingly at random and often in favour of poor quality Tesco own brand substitutes. The vegetarian section is a prime culprit for this. At one point vegetarian products were removed completely in favour of burgers(!?!). More recently, the available Quorn products have shrunk to favour Tesco stuff. The same with chocolate: why buy Lindt when you can buy Tesco's own. And tea. Branded Assam? Good gracious no, we want you to buy Tesco's (bad) Assam.
Fresh fruit and veg stock is often very poorly stocked with no indication that anyone is in a hurry to fill up the empty shelves. This doesn't appear to be a supply shortage, just a failure to get stock from the back and put it somewhere people can actually buy it with any sense of urgency.
I don't know how much stocking decisions are managed by the store and how much by Tesco centrally, but it is weird and extremely irritating.
On the store design side of things, whoever designed the new permanent store made the truly baffling decision to make half the self service checkouts mini-sized, so that if you have a lot of shopping you either have to wait for the larger ones to be available, or use the tiny ones and watch your bag fall off the scales because the scales aren't big enough. This was a well-used, major supermarket before the move. What were they expecting? For half the clientele magically to turn into convenience shoppers who needed smaller tills?
Tesco is a chain of supermarkets selling food, drink, toiletries and other household goods. They also offer a wide range of services, from loans to home shopping. Mobile top up cards and scratchcards are also available.
