A new counter-service café has landed at 1640 South Street in Graduate Hospital, and it's not interested in competing for dinner reservations. Sandpiper Café soft-opened this month with hours running 7 a.m. to 5 p.m. daily, staking its claim on the neighborhood's breakfast and lunch crowd instead.
The daytime-only model is deliberate. According to 6abc Philadelphia, Sandpiper is a partnership between Gunner Raharjo and Deddy Pornomo, who decided the Graduate Hospital neighborhood needed a space for casual morning fare. Customers can order at a counter or screen, then grab a seat at tables built for sitting, working or socializing, or take their order to go. As reported by the Philadelphia Inquirer, the café intentionally targets the neighborhood's daytime gap rather than jumping into the crowded evening dining scene along South Street.
Comfort Food, Coffee and Customizable Burritos
The menu leans into casual comfort: customizable breakfast burritos, bacon-egg-and-cheese sandwiches, salads and smoothies, per 6abc. Sandpiper also runs a barista-led coffee program, positioning it as what 6abc calls a daytime destination for comfort food, coffee drinks and smoothies. The outlet describes the café as a bright new addition to the Graduate Hospital neighborhood.
Raharjo is a partner at Indo Spice on West Passyunk, and the Inquirer's report notes that the Indonesian restaurant opened in spring 2025 and was named to the paper's list of the 76 most influential local restaurants. He's also a partner at Olivier Café in Old City, which the Old City District describes as a spot specializing in gourmet breakfast sandwiches, scrambles, pastries and barista coffee service — a menu concept that clearly carried over to Sandpiper's own lineup.
A Corridor Business Groups Have Been Cultivating
Sandpiper wasn't a surprise arrival. The South Street West Business Association introduced the café as an upcoming business at 1640 South Street during its June 2025 general membership meeting, alongside several other commercial developments along the corridor, the association noted on its Facebook page. Sandpiper now joins other recent additions on the 1400 to 1600 blocks of South Street, including Mod Spuds at 1424 South Street and Winners Ice Cream at 1620 South Street.
That clustering fits a broader shift that neighborhood planners have been pushing for years. Commercial corridor planning on South Street West has focused on moving the area away from its historic identity as a weekend regional destination and toward a balanced neighborhood model that serves local residents on weekdays with morning and afternoon dining, according to WHYY. The South of South Neighborhood Association, which serves Graduate Hospital from South Street to Washington Avenue, runs economic development programs aimed at recruiting small businesses into vacant commercial spaces along the corridor.
A Neighborhood With Rising Spending Power
The economics behind the daytime bet look favorable. Median household income in the Graduate Hospital cluster doubled over the past decade, climbing from $47,800 between 2010 and 2014 to $96,900 between 2020 and 2024, well above the citywide median of $62,000, per the Inquirer's analysis. Graduate Hospital also rates as a biker's paradise with a 98 Bike Score and an 87 Walk Score, generating the kind of steady foot traffic that supports quick-service counter ordering, according to Fresh Places Real Estate.
The building itself reflects the neighborhood's changing profile. The mixed-use property at 1640 South Street pairs ground-floor commercial space with residential apartments upstairs, where one-bedroom units were listed between $1,695 and over $2,000 per month this year, according to a Zillow listing. Hoodline previously covered cheap rentals at this address back in 2019, when the building's units carried far lower price tags than they do today.
Whether Sandpiper and its daytime neighbors can convert that steady weekday foot traffic into lasting business remains an open question for the corridor, one that business groups and residents alike are likely to watch as more counter-service concepts test the neighborhood's appetite for morning and midday dining.
