Why it's listed
Mastro's Steakhouse Houston (1650 W Loop South) is open and runs a transparent multi-origin Wagyu program. Its first-party menu lists Japanese A5 Wagyu from Miyazaki Prefecture and A5 Kobe Beef (100% Tajima cattle, Hyogo Prefecture), plus American Wagyu (WinterFrost) and Australian Wagyu (Westholme cross). The Miyazaki A5 clears full Japanese provenance (prefecture plus JMGA grade), qualifying the venue as verified. American and Australian offerings omit breed status and AUS-MEAT score, so they are not badged.
