I love aldi and my local one is really good though it seems they can vary in terms of range of items in stock and quality of fresh fruit and veg. The fact that yours is new and large (and possibly competing with a nearby waitrose?) suggests it should be well supplied!
It's definitely worth trying the aldi version of whatever you normally buy. You may find you don't like some items but that's possible whenever you change brands no matter what supermarket you shop in and doesn't mean you won't like anything.
We find their laundry detergent good though it's not as scented as the more expensive brands. I personally wouldn't pay double for stronger scent though! Their household cleaning stuff is all pretty good in my experience and their magnum original washing up liquid and the dishwasher tabs are better than some of the well known brands..
We don't eat meat but family and colleagues have commented positively. Their fish cakes are lovely, much nicer than I've had from other supermarkets (I cba to make them). Their fresh food items such as prepared salads, stir fry, deli items, desserts etc are good. Yes, it's cheaper still to make your own from scratch but if you don't want to then they're much more affordable and as good as you'd buy elsewhere
.
We also like their fresh juices, smoothies, yogurts, deli items, crackers, some breads, sushi, the occasional readymeal item for lunch for work. Their biscuits and chocolate are nice and they have some convenient frozen stuff - grain based, cauliflower rice as well as the usual frozen veg/meat/fish/pizza/ice cream. Any tinned stuff such as kidney beans, chickpeas, butter beans, corn, tuna etc have been fine.
I can't get everything I want there so still need to do a top up elsewhere but I think that's a small price to pay given what we do buy in aldi is @ a third cheaper.
