Cocktail Hour- variety and quantity, how much food do we need???

We are expecting 55 people.

Dinner will be soup, salad, entree. We are at a hotel, their portions are on the smaller side. So we want to make sure there's enough at cocktail hour.

The F&B director recommended a charcuterie station ($1100), and two appetizers: shrimp potstickers (75 pieces) and vegetarian spring rolls (70 pieces) which come to a cost of $555.

And that's it.

Seems like... not enough? Googling reveals anywhere between 2-7 pieces per person. I would love to hear from those who have either already had their weddings and can give feedback about not enough/too much food, or others who are having similar sized weddings and what you are planning.

Timeline- ceremony 4pm, cocktail hour 5pm, reception 6-10pm.

I am not looking to blow the whole budget on food because I know the bar bill will be heavy duty (they don't offer a package, it is pay per drink, settled after the event is over- does this make anyone else nervous). But at the same time, we have some very heavy drinkers and I want them fed and not wasted. I want the foodies content with full bellies.

Dessert is TBD. Definitely a candy table (halloween wedding), I hesitate to do a cake because a) it gets wasted, b) they told us anything served by staff can't be taken out of the room at the end of the night, including cake.... DOH rules??? c) I like the interactivity idea of a DIY dessert bar that I am responsible for, not the venue, to control costs. Doesn't have to just be candy, I can bring my own individually wrapped desserts (Hello Costco cookies!!!!!)

Thoughts? Thanks!
