After chasing one midrange bar-burger after another, looking for the best in the $12-$20 range, I just had one that topped them all...and I cooked it. Trader Joe's Steakburgers, grass-fed Angus, $5.79 for four 5 1/4 oz. patties, plus pre-sliced rounds of Pepper Jack and a package of the ciabatta buns. For a total of maybe $4.00 per burger (counting the Whole Foods $$$ heirloom tomato), and a few minutes with the grill pan, I managed to leave Ford's Filling Station, Second City Bistro, and even the Redwood in the dust.
Of course this does not mean that I'll never get another burger at those or other places...but it does mean I might feel a little smug in my evaluation of what I'm eating!
