Shares in Thailand's green tea and sushi restaurant firm Oishi Group PCL rose more than 10 percent on their stock market debut on Wednesday as investors bet on a booming local appetite for luxury consumables.
Oishi, which means "delicious" in Japanese, makes 80 percent of its profits from green tea, a health drink new to Thailand but already popular in Japan and Taiwan.
At its Oishi Buffet restaurants, punters pay a fixed price to eat as much as they can against the clock.
The stock opened at 25 baht and was the day's most active share, later slipping back to close at 21.30 baht up from its launch price of 19, as investors booked gains in a nervous market.
Thailand's 20th new listing of 2004 had a market value of around 4 billion baht ($95 million) at the end of trading.
