They're popular for many bargain buys - like their affordable award-winning wine - but now the budget supermarket chain managed to knock Waitrose off the top spot, a position they held for the past three years, thanks to their 'fantastic prices'.
In a survey, conducted from feedback of 6,800 customers across the UK, the German store was also awarded a five-star rating in value for money and an overall satisfaction score of 74 per cent.
The supermarket's rise to the top sees Waitrose actually fall to fourth place as consumers branded it 'a bit pricey', while Marks & Spencer bagged the second position.
Aldi's rival Lidl managed third place while Sainsbury's came in last, taking the ninth position as shoppers have been unimpressed with their special offers.
One person who will be extremely pleased with Aldi's top spot is two-year-old Michael Finn.
The toddler won the hearts of the internet after his mum shared a video of him in tears after learning he wouldn't be able to visit the shop on Sunday.
In the clip, little Michael is almost inconsolable after mum Kelly explains that the store closes early on a Sunday, therefore it was too late for them to do their food shop.
Sharing the video on Twitter, Kelly also cheekily asked Aldi if they would reconsider their Sunday opening hours.
She tweeted: 'Dear AldiUK, please consider longer opening hours on a Sunday. Much love, your biggest (and probably youngest) fan. Michael Jr. age 2.'
Unfortunately for Michael, it doesn't look like Aldi will be changing their hours any time soon.
A spokesperson for the supermarket said: 'It's always good to hear from our fans like Michael Jr, and we know it can be upsetting when we're not open.
'We close so our colleagues can go home to their friends and families, but we're open every day so hope to see Michael Jr back in store soon.'
