Order up some mint or chamomile. 喝薄荷茶或者洋甘菊茶

A steaming cup of one of these teas will quickly dispel that dyspeptic feeling. Simply use one of either kind of tea bag to a cup of water. Cover and steep for ten minutes before drinking. Many restaurants stock these two calming brews, so have it after dinner if you've eaten something rich that might not agree with you.
