Yes, they call it 'Deliveroo Editions'. They sometimes waive the delivery fee, has its own logo/category and you can mix the delivery from various restaurants
I don't think I've ever actually ordered from them, I'm not in the market for 20 quid takeaways.
When I had a look a few years back basically everywhere looked the same with stock professional photos. You wouldn't know that your fancy-looking Indian came from a grimy backstreet shop or container or whatever else.
I cook for myself and get higher quality food at a fraction of the price.
I generally reserve eating out for when I'm on the go or want to have a night out with friends. It's very rare that I buy takeaway food to eat at home. One of the best parts about being at home is having a kitchen.
Decent quality prepared food is expensive in a ton of places, this isn't an exclusively London thing by any stretch of the imagination.
One of your pleasures, which is awesome for you. I wish I enjoyed cooking, but I don't, so if you've been through this a million times maybe it's time to stop assuming it's some universal joy?
Absolutely does not cost £20 to eat in London, unless you live somewhere upmarket but in that case you can probably afford it. I can get good pizza for ~£7.
