I am having 20 family and friends at my wedding. looking for unusual finger foods/ appetizers.?

Sushi would be interesting...think 'California' roles......and other vegitarian type sushi......chicken wings are always welcomed, if you go with sushi as well think a sweet & sour or teriyaki sesame wings...coconut shrimp on skewers.....or small pieces of marinaded meats skewered and grilled....have dif dipping sauces available......a cheese fondue with several dif breads maybe rather 70's but it's coming back into vogue.....
