A PUB which advertised a deal on "Irish Car Bomb" cocktails in Bristol has covered the advert after angry locals complained. The Brass Pig pub, which is close where two bombs exploded in the 1970s, put up the banner to promote its St Patrick's Day celebrations. Pub officials said the advert was "wrong" and covered the offending part of the banner. Bristol was bombed twice - in 1974 and 1978 - both on sites near to the pub. The first attack, which was blamed on a Bristol terror group, happened on nearby Park Street on December 18 1974. Around 20 people were injured in the bombing. Bristol was targeted in a series of IRA attacks across England on December 17 1978. Around 18 people were injured when a bomb went off in Maggs Department Store in Clifton. Other IRA bombs exploded in Bristol, Coventry, liverpool, Manchester and Southampton on the same day. The Irish Car Bomb cocktail, sometimes known as a Belfast Car Bomb was invented at a bar in Connecticut in 1979. The cocktail is made by adding Baileys and Irish whiskey to a shot glass. The glass is then dropped into a half-pint of Guinness and drunk quickly before the mixture curdles.
