1. Preheat the grill or broiler.
2. Using a pastry brush, spread the inside and outside of each bun with the melted butter. Grill or broil the buns quickly to warm them through. Set the buns aside.
3. Combine the mayonnaise, lemon juice, and salt in a bowl, and mix well. Fold in the celery, shallot, tarragon, parsley, and chives. Then fold in the lobster meat. Place 1 bun on each plate, and divide the lobster salad evenly among the buns.
4. Serve immediately, with potato chips alongside.
