I'm having a small dinner party for a group of people who have some overlapping but different needs and preferences. 8 people total. One is a dairy and gluten free pescatarian, one is allergic to onions and dairy, one eats everything but fish (just doesn't like it), one is allergic to shellfish. I want the meal to be summery, but feel special for a party. I don't feel that every dish has to be consumed by every person if I have three or four dishes. Any ideas are appreciated!
