Here is a simple recipe for bananas foster from Brennan's in New Orleans. It's a good crowd pleaser if you make it at the table with an alcohol burner.
Melt butter over alcohol burner or in attractive skillet. Stir in sugar, cinnamon, and banana liquor, and heat a few minutes. Add bananas and saute until slightly browned. Add rum, heat well, then tip pan to ignite. ("This is unnecessary without an audience, unless you like fire." The alcohol will boil off after about 2 minutes.) Sift bananas carefully out of pan, place four pieces over each scoop if ice cream. Spoon sauce over top. Serves 4.
