Not personally but 2 friends have, one was didn’t work, one is working as we speak.
The on that didn’t work had all the attributes you want. It sold genuinely award winning food (with a good profit margin), it was different enough to stand out without being gimmicky, it was a lovely place to spend time and people who went there recommended it. It failed for 1 reason, the location. It was in a new build complex with virtually no passing trade and you had to pay to park anywhere near it, he took the location as they were doing preferential rates for new businesses. No people = no money, no matter how good your product is.
The one that is doing OK spent a lot of money on a High Street location, a LOT of money. He has passing trade, is selling a lot of stuff (coffee and brilliant cakes mostly) but is still struggling to make much money. He breaks even, just, and this is because you need to sell a hell of a lot of stuff just to pay the bills. He works full time during the week and at the shop in the weekends, his wife is full time a the shop and doesn’t take a wage. He has, after a beer or 2, described it as one of his worst decisions.
Personally, after what they have experienced I would go nowhere near such a venture…
