CHICAGO (AP) _ Two hooded gunmen entered a North Side tavern and opened fire early today, killing one person and wounding three others in what police described as a street gang shooting.

''It is normally a quiet place,'' said an unidentified employee of the Over the Hill Tavern. ''But once in a while, some gangbangers hang out here.''

Police said Darryl Griggs, 21, died from a chest wound.

One of the wounded was in critical condition in St. Mary of Nazareth Hospital with a gunshot wound in the stomach, said hospital spokeswoman Gillian Pines. The two others wounded, one a bartender, were in fair condition at another hospital.

Patrolman Bruce Hoffman said the gunmen were aiming for Griggs, who apparently was the leader of a rival street gang.

An employee of the tavern who refused to give his name said he was in his apartment above the bar when the shooting occurred, but said he was told by another employe that two men entered the bar ''looking for a man called the 'Bulldog.'''

After spraying the tavern with gunfire, police said, the pair fled on foot. It was not known how many people were in the tavern at the time.

Police Communications issued an all-points bulletin for two white males between the ages of 25 and 30. Both men had hoods over their heads and were armed with pistols, the bulletin said.
