In a large bowl, combine the blue cheese, vodka, dry vermouth, olive brine, chopped olives, a generous crack of black pepper, and a pinch of celery salt. Lightly mash some of the blue cheese into the liquids while leaving plenty of crumbles intact.
Add the hot, freshly cooked fries directly to the bowl, then if using add a little garlic butter on top, and quickly toss until lightly coated in the blue cheese mixture. You want little bits of blue cheese and olive clinging to the fries rather than a heavy, wet coating.
Transfer immediately to a serving platter and finish with more chopped olives, fresh dill, lemon zest, and plenty of cracked black pepper. Garnish with a cocktail pick of olives and serve right away.
