Hanger steak

Occasionally seen on menus as a ''bistro steak'', hanger steak is also very traditional in Mexican cuisine, particularly in the north where it is known as arrachera, and is generally marinated, grilled and served with a squeeze of lime juice, guacamole, salsa, scallion and tortillas to roll tacos. In South Texas this cut of beef is known as fajitas arracheras. It is sometimes incorrectly referred to as flap steak or flap meat, which is a distinctly different cut.

Available options:
1). no.
2). yes.
