I like the concept.  Roll fresh \"Angus\" beef into meatballs every AM.  Smash them just before cooking.  But in reality, all beef is Angus.  It's the most popular type of cattle in the US.  And they must use the lowest fattiest (85%?) cut because the burgers are greasy.  And they come in either 5oz or 7oz patties.  Got a small smash and a side salad.  The salad was OK.  Burger with lettuce wrap had no wrap.  Just lettuce and tomato on the side.  So I had to eat my burger off the plate.  And it was greasy.  So not sure what to make of SB.  May try it again, but with In and Out so close, it's tough to make the move to SB.  If only In and Out had sweet potato fries!
