Steven, the burgers at steakhouses you refer('very high quality meat'). What cut of beef, do these steakhouses generally use for their burgers? I ate a burger at a top steakhouse here, they use ground sirloin if my memory is correct. Most of the best burger places use ground chuck(or a mixture featuring ground chuck) it seems. Are Angus burgers anything special-beyond using angus beef? My pet peeve with many restaurants serving burgers, is that they often overcook their burgers. I always order my burgers cooked medium, but rarely get it that way. With Mad Cow worries by the general public, I might never get a medium done burger ever again at a restaurant!
