I am planning a French inspired B-day (34 yrs) party for my BFF, with a strawberry crepe cake. What else can I serve to fit the party theme?

Champagne to start. While you're sipping, munch on popcorn popped in olive oil and drizzled with truffle oil. If you can find truffle salt sprinkle it in top along with coarse salt.

cheese is last course,of course!

make a bunch of croque monsieur sandwiches and cut them into small triangles!

And think about gougieres (savory cream puffs) - always a hit with a glass of wine!

Consider a charcuterie with various cured meats, cheeses, small pickles, breads, and jams, and olives.

Serve it on a big wooden board...or a sheet pan wrapped in brown butcher paper. With mustard on the paper. and jam in piles. Very free form rustic.
(Bonus point if you find wooden Popsicle sticks for the people to use as spreaders)

I'd take a big half sheet pan..and wrap it in brown butcher paper..and plate most of things on that...meat, cheeses, olives, pickles, and have another basket or bowl with a cloth for the bread...baguettes, croissants, flat breads.
