OK-so the first time I went to Shake Shack I didn't give it a fair "shake" having just had a burger at Molly's (and fries and a couple of pints of Guiness)and it was 11 at night (although no lines at that hour). So I got on line at 11 in the morning (almost no line) and tried a shack burger and a regular cheeseburger for comparison and a concrete. Concrete was pretty good but not as good as the old Custard Beach place that recently went out of business (damn). At the risk of getting "flamed", the burgers just didn't cut it. First tip off was when they didn't ask how I wanted them cooked. Of course at a mere 4 ounces there isn't really any choice other than to cook it medium/well (I prefer rare). Soggy buns under heat lamps-not toasted-another hint. Mix of raw meat-sirloin and brisket-no chuck? Final blow-lettuce and special sauce, i.e. MAYO! Yuch. All I can say is that it was indeed a superior burger but only if you're comparing it to the most similar one in my experience...Johnny Rockets.
