Tradition.
The Rainbow Coffee-house, near Temple Bar, one of the oldest taverns in the metropolis, was kept by James Fan, a barber, soon after the introduction of coffee into England. Three years previous to the Restoration, anno 1657, he was presented by the Inquest of St. Dunstan’s in the West, “For making and selling a sort of liquor called ‘Coffee,’ as a great nuisance and prejudice of the neighbourhood,” &c. Strange as it may appear, within half a century of this period, namely in 1708, there were upwards of three thousand Coffee-houses in London alone. An old author says, Who would have thought, after the prejudice against coffee, which was considered pernicious and a public nuisance, it would have been, as now, so much drunk “by the best of quality, and by physicians?”
