Preheat your grill or stovetop grill pan to medium-high heat.

Season the steak with salt and pepper on both sides. Grill the steak to your desired doneness. For a medium-rare steak, cook it for about 4-5 minutes per side. Adjust the cooking time based on your preference. Once cooked, let it rest for a few minutes before slicing.

In a large skillet, melt 2 tablespoons of butter over medium heat. Add the minced garlic and cook until fragrant, about 1 minute. Add the shrimp to the skillet and sauté until they turn pink and are cooked through, approximately 2-3 minutes per side. Remove the shrimp from the skillet and set aside.

In the same skillet, add the remaining 2 tablespoons of butter and melt it over medium heat. Add the lobster tails and cook for about 3-4 minutes per side, or until the meat is opaque and cooked. Remove the lobster tails from the skillet.

Serve the sliced steak, shrimp, and lobster tails together on a platter. Garnish with freshly chopped parsley.
