Used to be a "Beef-A-Holic" back when I ate red meat.
Never tried Kobe. Argentinian? Did not find it special.

It's been 10 or more years, but I thought that Chicago had the best beef. Consistently, restaurant to restaurant. You name a decent restaurant in Chicago, I thought their steak was great. Time after time. Gene and Georgetti's was one of my favorite haunts for a great steak.

These days, I have lost my taste for it. Ordered a steak about a year ago after a 9 year hiatus. Could not eat it. Shame. I guess my arteries are thanking me somehow.
