Having lived in Manhattan, Ive been to Peter Lugers various times.... and agree that their Porterhouse is excellent. I have great respect for some of the top quality beef made in the USA... even though its mostly grain fed (and not grass fed, as is my preference) the best US beef is indeed top notch. Ive not eaten at Vlado's in Melbourne so Im afraid I cant comment... but I also rank Australian Beef as having mostly top quality.

On the Lomos with sauce.... well Im actually not a huge fan of eating TenderLoin because I find it too "healthy" and bland.... and it usually requires sauce. I tend to prefer more "wild and gamy" cuts... ^
