My sister tried the steak at the QS in America - it was shoe leather. I would not recommend it.
For TS steaks, I've had very good steaks at Captain's Grille, Sci-Fi, Raglan Road and Chefs de France. I loved the Raglan Road steak but I let my dad try it and he hated it due to the glaze on it - so if you have a picky steak eater, that might not work.
