WeBuiltThisBuffetOnSausageRoll Love your posts and absolutely agree that you're not BU.
I used to be a nearly complete non-cook, so eating out was essential. In the 'olden days', when - as previous posters have pointed out/queried - there were no chains (just Wimpy, I think) - this meant either independent restaurants or hotels. Hotels were often an absolutely brilliant option: you could dine in their restaurants and have a superb meal for a (relatively) good price.
However as chain restaurants took over the high street and as I learned more about the (ersatz) food they provided (thank you Joanna Blythman, Felicity Lawrence et al.), I finally had to come to the conclusion that home cooking was best. Not only best but terribly necessary.
So I bought a Thermomix (a touch over £1,000 just over seven years ago), and taught myself to cook at home. From real scratch. Restaurant-quality meals.
What a revelation! Now I don't have to consider whether or not restaurant meals are 'fake'/centrally pre-prepared/manufactured or whatever - there's no question because I have a comparison; my taste buds tell me.
From eating out several times a week, and invariably at weekends, we now eat out about three times a year. The food budget has dropped through the floor (and we only buy organic - !), and our meals are just better: more taste, more interest, fresher.
Dinner invitations, which used to be accepted or declined on the basis of guests being available ("Sorry, we can't do any time this month") are now begged for ("I'm being cheeky, I know, but may we come to dinner again soon?") and I actually host Christmas dinner. My (compulsory year) ex cookery teacher would be shattered!
The more you cook from scratch (really from scratch: I make the mustard, the sauces, the butter, the stock...), the more you understand how food is made and how it should taste. Consequently the more you realise how crap is restaurant food (and the ingredients in supermarkets).
The other aspect to this is health. Crap in, crap out, basically. If you eat the offerings of the food manufacturing industry - whether in restaurants or in the supermarket - you won't thrive. If you eat fresh, well sourced, food then you will.
The average estimate of my or my partner's age is around ten years younger than the reality. A common response to people seeing either of us after a long absence or for the first time is "You look healthy". And, despite our rather advanced ages, we're not on any medications and shrug off and/or just don't get viral infections.
Food is what you are and how you live and thrive. This is not a side issue - it's vital.
Good thread, OP.
