Tips on hosting a dinner party for his workmates needed!

Hi ladies!

In my fiance's research position at school, the tradition is for him to hold dinner parties and small get togethers for his labmates, classmates, etc.

I want to be helpful and leave his guests with a great impression, positive thoughts, and confidence in him as a new addition to the team!

He has asked me to help him make this a success, and I'm overjoyed! I always saw a little Bree VanDeKamp in myself, haha. Problem? I've never done this before! I've never even hosted a party. I checked the search bar and I've done some Googlin', but I trust you ladies to be able to give your own pointers from experience.

My main priority is to make him proud and give a great impression, making him look good. So truly any tips -- from menu to conversation to whatever else -- are very welcome. I'll be doing this a lot over the next five years.
