Had the summer special of top sirloin steak with shrimp and chicken. The shrimp was great, chicken breast was ok, the steak was terrible. Had a piece of muscle tendon or something in it that was so tough, I couldn't even cut it. Had to trim the meat around it to eat it in tiny ripped off pieces. For a "steakhouse" as in the name of this place, that was the worst steak I ever had. Where's the quality control?
Flip side of it, my mom's steak was perfectly done medium.
Service was ok, server hardly made eye contact while talking which was a bit uncomfortable.
