Steaks: we serve US Certified Angus Beef, American and Australian 'Kobe', and 100percent Japanese Wagyu imported from New Zealand. (A5 from japan returning later this year) A5 stands for the highest grade of beef in the world 5A5: 5 senses/the A5 experience. 5A5 Steak Lounge is conveniently located in the northern FiDi, perfect for happy hour, dining, and late night cocktails.
