In the early ‘90s, I was at uni and in a house share. We took turns cooking veggie from books like Anna Thomas’s The Vegetarian Epicure (one of my former housemates recently remembered our typical dinners as “things on pasta or rice”). We borrowed a friendly professor’s car to stock up on 24-packs of cheap beer in cans, drank tap water, and knew the cheapest things to order when we hung out for hours at the cafe/bar on campus (grilled cheese sandwich and chamomile tea for me).
Once I started working full time and had a bit more money, my focus shifted from “cheapest possible” to “cheap and convenient”. I worked for a US investment bank for a few years and they bought us lunch (ordered in for delivery - we had a choice of about 5 menus) every day - bliss! My favourite place had huge main-dish salads and you could choose exactly what you wanted from dozens of ingredients. It only occurred to me later that yes, we were also working through lunch every day with no extra pay. We also went out to eat with clients a lot and the company paid, so I ate a lot of salmon, scampi, and scallops (colleagues appreciated the steak, but I was/am pescatarian) and drank a lot of comped cosmopolitans, greyhounds, and martinis in those days! I had a flatmate who considered himself a bit of a mixologist and made weird cocktails at home on the weekends - I remember balalaikas, grasshoppers, manhattans, and frozen mudslides. I also remember sushi being our favourite splurge for non-work meals out.
By the end of the decade, close to thirtyish and “nesting” in London, I was actively avoiding eating dinners out. A toasted bagel and coffee or a smoothie on the fly for breakfast and sandwich-salad-soup for lunch were fine, but dinner at home was sacrosanct. By the early-mid ‘00s, Donna Hay-style cookbooks ( New Food Fast ) were my bible, and a < £10 bottle of drinkable wine was the holy grail.
Looking back, I think the biggest difference was that we relied a lot more on physical experience and word of mouth or on what was around us and we didn’t have - or at least, didn’t fully use and didn’t take for granted - the whole world of possibilities now available through the internet.
