The Bulls Head on the corner of Deansgate and Wood Street (so near to the modern day Hog's Head) was described by Manchester police as the "worst pub in town" in the 1840s. The licensee's convictions equalled those of most his customers - "thieves and prostitutes of the very worst description" - and the Bulls Head would open all night to satisfy them. Somehow it kept its licence and in later years was seen to advertise "gentlemen-only" concerts and its own shooting gallery . Other dodgy boozers of that period listed include the Dog & Rat, the Red White & Blue, the Old Ship, the Pat M'Carthy the Green Man (but with no further information they'll be added to the unknown pubs list).
