Well, I believe I found it — or, should I say, them.

The filet mignon (or bife di lomo) at Cabaña las Lilas in the Puerto Madero section of Buenos Aires in Argentina definitely edges Shula’s in terms of flavor.

However, Rio Alba in Buenos Aires would edge Cabaña las Lilas because it serves a substantially bigger cut of filet mignon at a less-expensive price. The quality of the beef even seems superior to that of Cabaña las Lilas, but unfortunately the flavor is relatively rather bland.

If the filet mignon at Rio Alba had the intense flavor of the filet mignon at Cabaña las Lilas, it would have been unquestionably the best filet mignon I have ever had.

In my opinion, because of the respective features outlined in this milepost, the filet mignons from Rio Alba and Cabaña las Lilas are tied for the best cut of filet mignon in the world, followed very closely by the filet mignon offered by Shula’s.
