Back in February, word broke that the Causwells team was plotting world burger domination with the arrival of Burger, a pop-up with permanent ambitions focused solely on that popular Causwells patty. In the months since, the name has changed to Popsons, and the permanent part has arrived. Starting next Tuesday, January 26, Popsons will open for lunch in the former Marlowe Burger location. And there will be many burgers. The menu revolves around the critically-acclaimed hamburger, but with chili and bacon blue variations, plus some salad and chili. Notably, there will also be French fries, unlike the onion rings that currently come on the side at Causwells. You can see the full menu, with prices for single and doubly patty versions, below.
Chef Adam Rosenblum, who developed the burger, is a partner in this project along with restaurateur Alvin Garcia, and the duo already have another location in the works at 998 Market St. in the Warfield Building, set to debut this March. For the first three days, Popsons will only serve lunch from 11 a.m. to 3 p.m., adding dinner service on February 1 and staying open from 11 a.m. to 8 p.m.
