As if a new year would slow the Umami Burger crawl across the Southland. Next up: the growing burger behemoth will take over the former Papoo's Hot Dog Show, a funky corner institution that served the Toluca Lake-Burbank neighborhood hearty breakfasts, hot dogs and beer from 1949 to 2011. Umami will keep much of the exterior intact, including the iconic "Show Burger" and "7 Varieties Hot Dogs" signage (and we hope the wiener dog-hot dog-angel topper), but inside the menu will be reinvented. So that means Umami hot dogs, people. There will also be burgers of course, plus breakfast, organic milkshakes, beer and wine. Look for the opening by summer (4300 Riverside Dr.).
