I'm having a party for 50 people in my home, hopefully with somewhat staggered arrivals so it isn't ridiculously crowded. I will have a ham with rolls/mustard/pickles, and shrimp cocktail. The last time I had a party I was in graduate school and so the nibbles were on the "beer and chips" end of things. I would like to do it a little more nicely this time. Ideas for what to serve? I can farm out some requests to friends for cheese/cracker platters, vegetables, salads, that sort of thing. I will have two people available to clean up and warm things in the oven if needed. What kinds of food work well at a party over several hours? Also, I have no concept of how much wine and beer I should provide. May I please benefit from your experience? Thanks!
