Rooster Soup Co.: Luncheonette with a social side

Rooster Soup Co., a luncheonette that opened this week on the lower level of 1526 Sansom St. (215-454-6939), teams the crew from Federal Donuts with Broad Street Ministry, whose anti-hunger Broad Street Ministry Hospitality Collaborative will receive the profits.

The idea came from Steve Cook, a partner in Federal Donuts and the CookNSolo restaurants (Zahav, Abe Fisher, and Dizengoff). Cook noted that Federal Donuts had no use for the backs of the chickens it prepares and thought they could be used to make soup.

Chef Erin O'Shea, formerly at Percy Street BBQ, offers an easy-on-the-budget menu with a Southernish spin. Hours are 8 a.m. to 8 p.m. daily. Breakfast (till 11 a.m.) includes stick-to-your-ribs fare. Lunch includes four soups, four salads, and four sandwiches, and dinner includes a nightly blue-plate special.

There is a vegetarian item in each category, and four beers on tap, plus canned wine and classic cocktails.

Design includes an 18-seat counter and bar and booths along the side in the main room. Up a few steps in the rear are tables able to seat larger parties.

The crew from Chinatown's Shanghai 1  has branched out around the corner with Dumpling, which recently replaced Erawan Thai (925 Arch St., 267-534-4141). Eleven kinds of dumplings make up only a part of the menu, which is nonspecific to one particular region of China (whereas Shanghai 1 is Shanghaiese/Taiwanese). Hours are 10:30 a.m. to 10:30 p.m. Sunday to Thursday, until 11 p.m. Friday and Saturday. Lunch specials ($7.95) are served 10:30 a.m. to 3 p.m. weekdays.

Chad Rosenthal has expanded not only his banh-mi-to-go empire but its menu. Rosenthal, who opened Banh Street in Roslyn in late 2015 (following the Lucky Well in Ambler), has opened a second location, at 832 N. Bethlehem Pike in Spring House (267-419-8587), and this shop also sells fried chicken flavored with Vietnamese-inspired sauces, in addition to the hoagies. Hours are 11 a.m. to 8 p.m. daily.

King of Prussia Mall is bringing in four more eateries, in addition to the previously announced Mistral, due later this winter, and True Foods Kitchen (June). They're all branches. Outback Steakhouse is due near Primark around Valentine's Day; Yard House, a sports bar with a huge beer list, is due near Primark in March; Australian-themed coffee shop Bluestone Lane is due in April in the expansion area near Clarins; and lobster-roll specialist Luke's Lobster is due in early May in the Savor dining area (near the new Taco Truck).

El Compadre, the South Philadelphia Mexican restaurant whose 23-year-old owner, Isaías Berriozabal-Martinez, died unexpectedly Jan. 11, has reopened. Ben Miller, his stepfather and the co-owner of South Philly Barbacoa with Berriozabal-Martinez's mother, Cristina Martinez, said regular hours were 6 a.m. to 3 p.m. weekdays, 11 a.m. to 8 p.m. weekends. ... Saturday will mark the last day for Arterial Agents, the coffee shop that opened in May at Seventh and Sansom Streets.
