Depends on the group. Is everyone American? I’ll assume yes. How about:
Chicken salad
Mixed green salad with apples, walnuts, and raspberry vinaigrette,
Cold orzo with spinach and light olive oil,
I guess some choice of bread
Salmon croquettes or crab cakes
Orange juice and mimosas
Various soft drinks and/or iced tea
Hot tea and coffee
However, since it is at 2:00 maybe you are not really planning in feeding them a meal, but more appetizer oriented?
I would still have the mimosas and other drinks, maybe a couple dips, chips, pita, bagel,
hummus,
mini kabobs
toast tips, cream cheese or creme fraiche and smoked salmon.
Stuffed mushrooms
Or, the filo dough finger foods stuffed with spinach or mushrooms.
Or, if you are clear to people it is a dessert party, which you can do because of the time of day, you can do a Viennese table with:
Petit fours
Mini linzer torte
Lemon squares
Brownies
Mini pecan pie squares
And a fruit compote or fruit salad
With coffees and teas.
