Pre heat the grill to 350 F.
Place a pan over medium heat, and add in the butter, garlic, lemon juice, Old Bay seasoning, and parsley flakes.
Mix the butter sauce until everything is well combined, then remove the pan from the heat.
Cut the top of the lobster tails with kitchen shears midway down the tail.
Use your fingers to detach the meat from the inside of shell, then rest the meat on top of the lobster tail.
Drizzle a couple teaspoons of the butter sauce on top of the lobster, then place the lobster tails on the grill, with the meat up.
Close the grill for about 5 minutes.
Brush more butter on the lobster, then flip the tails over.
*I flipped the tails every 5 minutes, and grilled for a total of 15 minutes or so*
Serve, with the remaining butter sauce, and desired sides.
