Thanks to the thread a few lines below, I've found a new favorite burger.
I avoided the megafauna "Royal Burger" and tried their King--marvelous! nearly melt in your mouth meat, nicely seasoned, amply-portioned. I had them toss on an egg in honor of the late, lamented Meatty Meat Burger's version of the king and I have to say this one at least equaled MM before their fire (and subsequent modest decline in quality).
Also had a cheap gringo-style taco that was okayish.
Also noticed chilli in various modes (chilli fries, bowl of chilli, chilli on burger).
But I'll be back for that burger.
