Average weddings in the NY/NJ area are similiar to yours including all the flowers in the church and at the reception place - the only difference appears that we typically have a 5 course sit down meal which comes after a stomach blowing extravaganza which is the full buffet style cocktail hour. The cocktail hour has MORE food then the actual meal - lol
Here's the list from my wedding 12 years ago of JUST the cocktail hour:
Butler Service Hour d'ouvres Passed on Silver trays
Miniature Beef Wellington
Shrimp wrapped in Puff Pastry
Skewered chicken filet w/ honey mustard sauce
Aparagus speares en croute
Salmon Fritters
Baby Lamb Chops
Scallops Wrapped in Bacon
Veal Sausage in Puff Pastry with Dijon sauce
Stuffed Mushrooms with Chiclen Liver Mousse
Cold Buffet
Bruschetta blah blah (I will leave off the flowery speech on this one we all know it's tomatoes on bread)
International Cheeses with French Bread
Assorted fresh cut fruit and berries
Seasonal raw vegetables with assorted dressings
Mozzarella with Tomato and Basil
Marinated WIld Mushrooms
Seafood Salad of Shrimp, Scallops, Calamari and Mussels
Smoked Salmon with Capers and Onions
Seafood bar
Bar of Shrimp and Oysters on a bed of crushed ice with cocktail sauce and lemon wedges
Hot Buffet
Paella with lobster claws, shrimp, clams and scallops in saffron rice
New Zealand Mussels Marinara
Tenderloin Tips with Crushed Black and Green Peppercorns
Baked Clams Oreganata
Boneless Chicken Filet with Champagne Mustard Sauce
Captain's Station
Seafood Newburg, shrimp and scallops in Lobster sauce
Sauteed Shrimp Scampi
Roasted Breast of Duck a l'orange
Fusilli and Ziti offereed with Afredo, Tomato and Basil and Pink Vodka Sauces
The above is a typical cocktail hour. My actual meal was:
Lobster Bisque
Caesar Salad
Penne Marinara
Main course either Chateaubriand with Perigourdine Sauce or Boneless Capon Breast with Herbed Stuffing
Pastry Sampling plate per each guest plus Wedding Cake.
We had a 6 hour reception with a full open bar.
At my ceremony which was held in a local 175 year old church we had a soloist singing plus an instrumental quartet. At my cocktail hour we had a different 4 piece instrumental quartet at the reception itself my father - who paid for the whole thing - wanted a swing band

I protested at the froo frooness(new word here - lol) of it all and insisted on a DJ as I wanted some obnoxious music and DANCING and I hate how most wedding bands sing current music!
