"It's secret and Myanmar's government has told me what kind of food Thein Sein doesn't eat," Samak told reporters at Government House before chairing a weekly cabinet meeting.
"I went to buy stuff yesterday morning," he said.
Samak will host a private dinner Tuesday night for the Myanmar prime minister at his residence on the northern outskirts of Bangkok.
Samak is a known connoisseur and previously hosted a cooking programme on Thai television until the channel closed down.
General Thein Sein is due to arrive in Bangkok Tuesday afternoon for a three-day official visit.
