Yes, they opened a branch in Islington a few years back
Cannot afford Waitrose?! For lots of things they charge the same price or less than everyone else, particularly if you are willing to swap a branded product for Waitrose Essentials, which for lots of things tastes the same. I absolutely love Waitrose because the shops look great, staff are friendly, produce is brilliant and the range is inspirational. I also like the fact that in my two local branches instead of multiple queues there is one single maze queue and a maître d' who accompanies you to the next free cashier. It's much fairer and quicker.
I don't do all my shopping in there, as I'm someone who can only tell the quality difference in a few items; my weekly shop is done in Sainsbugs, but for items which cost the same, vegetables (better quality in Waitrose), ethical goods or items which Sainsbugs don't sell (like that lovely goats cheese available from the cheese room) or ad-hoc purchases it's gotta be Waitrose! If someone tried to work me out through looking in my kitchen or at my till receipts they'd struggle; it contains a nice mix of: brands (eg. Walkers), Sainsbugs Basics, ''Taste the Difference'' and bits and bobs from Waitrose too.
