It is Mumbai's favourite festival and is celebrated each year with fervour and frenzy. But when the city welcomes "Ganpati Bappa" this Friday, the celebrations will be low key. With a cap on the size of idols, ban on processions and restrictions on devotees visiting pandals, celebrations are toned down for the second year in a row. Festival budgets have shrunk and as a result, corporate sponsorships have dried out.
