Just regular American food

You cant get it wrong with some grilled cheese burgers, spaghetti casserole, green beans, maybe prime ribs if it fits into your budget. 

Americans are not interested in food only when they come to a gathering. It's about socializing. Ditch the long Chinese food menu.

You risk to garner some ingenuine praise on food they don't really like. Save the ethnic food for your church's potluck party.
