NOLA Style S&G Recipe

I make a decent shrimp and grits but want to prepare a bit more of a suped version next week. I've been to several restaurants where there's like a gravy on the dish, and it just takes it to the next level. Found the recipe below, supposedly copying a place called Pascale's, and curious if this looks legit to you cooks from LA.

Ingredients
Grits
1 cup stone-ground grits
2 cups water
2 cups whole milk
1 cup shredded Romano Cheese
Shrimp
1 tablespoon butter for sauteing shrimp heads
2 pounds large shrimp heads on are preferred
1/4 pound butter
1 tablespoon minced garlic
2 tablespoons Worcestershire sauce
1/2 cup beer Budweiser, Abita, or other light tasting beer
1 tablespoons cajun seasoning like Slap Ya Mamma
1 teaspoon crab, shrimp & crawfish boil
1/2 teaspoon thyme leaves
1/8 teaspoon oregano
1/2 teaspoon rosemary leaves crushed
5 tablespoons butter for finishing dish
