Two rows of men greet demonstrators at the main entrance to Tahrir Square, clapping as people enter, and chanting in the rhythms of a traditional Egyptian wedding procession.

"We are becoming bigger!" they shout. "God is Great!"

Inside Cairo's main square, musicians stroll, a man reads poetry to the crowd and vendors hawk potato chips, tea, hot food — even socks.

Tahrir Square, the scene of deadly battles with firebombs, rocks, horses and camels just last week, has taken on a carnival mood in the past few days as demonstrators try to establish an enduring presence, complete with food and entertainment, in their campaign to demand Egyptian President Hosni Mubarak's ouster.
