I would rather eat at a proper chain restaurant than a faux named chain. Yo sushi rather than Carluccios any day.
I wouldn't eat in either through choice, but if forced to choose, I would go for Carluccio's - faux named or not, the food is better than at Yo Sushi IME. And at least it was started by someone who actually knows and cares about food. I remember when Yo Sushi was launched by Simon Woodroffe in the late 90s, a a time when kaiten was a brief fad in London, and it was always a purely commercial venture. Which, to be fair, is probably why it has been so successful (although iirc it has nearly gone under a few times). But it was always inferior to the decent kaiten places, like the excellent Moshi Moshi Sushi - which, apparently, is still going in its original Liverpool St site, though I've not been for many years.
I used to go to the original Harry Ramsden's in the early 90s. Given that the original Harry Ramsden died in 1963 and apparently sold the business in 1957, he wouldn't have had much day to day involvement when I was visiting. It had already been taken over by Barnes & Richardson by then and was starting to expand, but only had a few branches, and the original still felt like a proper fish and chip shop - and was very good indeed.
It would take a lot of persuading to get me to eat in a branch of Harry Ramsden's now.
Also used to eat at the original Wagamama in Lexington Street, when it was a one-off. I remember the kerfuffle when they opened their
second branch. Surprisingly, though, Wagamama still seems to be fundamentally the same as it always was - though it's certainly possible that my memory of the original has been dulled over time and maybe the current incarnations are a pale imitation of the original. I would still eat in Wagamama though.
