Starbucks is revamping its strategy to lure Indians, including children, with smaller, cheaper beverages as it looks to expand in small towns amid a fierce challenge from domestic startups in one of its fastest-growing markets.

Among the first foreign coffee brands to enter tea-loving India, the U.S. giant has taken almost 11 years to open 343 stores, in contrast with private equity-backed chains Third Wave and Blue Tokai that opened about 150 in the last three years.

"As you grow in size, you need to get new consumers," said Sushant Dash, the chief executive of Starbucks in India, adding that the chain's "pricing play" would help shatter a perception that it is expensive.
