There used to be a cafe like this near me in SF. Unfortunately the zoning board ruled that it was more like an office than a cafe, meaning not permitted in a retail space.
Don’t do this unless you want to get shut down.
This isn’t just “the fun police” either. Pre pandemic SF was very sensitive about tech workers/offices crowding out other elements of the city. Work-friendly cafes would be immensely popular, meaning they would take up a lot of retail that could otherwise have more “character.” Now with so much commercial and retail vacancy it’s less of a zero sum game.
