The Richest Burger i Have Ever Had

I visited the Red White and Blues Grill on Friday .Where i order the burger of the week . Which consist of a brioche bun with 100 % Kobe beef top with bacon lettuce tomato Deep fried onion fingers baby shrimp and a craw fish consomme reduce down to a demi-glace . The richest burger i Have ever tasted . Not the best but definitely worth eating again . The bun was soft and full of that amazing flavor of butter .The patty itself was cooked to a medium rare perfection . All the topping even the craw fish sauce balanced the richness of the meat and bun . I definitely want this recipe especially the the craw fish sauce .
