Brandywine Realty Trust opened The Brandywine — a Marriott Bonvoy Tribute Portfolio hotel — at 165 King of Prussia Road on Friday, May 15, marking the most consequential hospitality opening on the Main Line in several years. The boutique property features 121 guest rooms and suites, flexible meeting space, an expansive roof deck, and two restaurants whose combined seating approaches 260.
The anchor restaurant, Merrick's Tavern, opened on Saturday, May 16, serving regional American classics for breakfast, lunch, and dinner, with a bar oriented to bourbon, rye, and local beer. The companion venue, the Pomelo Rooftop Terrace, opens with the property and features outdoor seating with views over the King of Prussia Road corridor. A Brandywine spokesperson described the project as a "cornerstone" of the firm's 2.1-million-square-foot Radnor portfolio, which has been built out over more than a decade.
The opening completes a development arc first announced in 2023 and detailed in further filings throughout 2025. The Philadelphia Inquirer first reported the $60 million price tag in February 2026. The hotel is expected to draw a mix of business travelers connected to the surrounding Class A office campus and regional leisure visitors drawn by the Main Line's dining and shopping circuit.
For Radnor, the consequence runs beyond ribbon-cutting. The Brandywine adds significant new evening and weekend traffic to a corridor whose pedestrian and parking infrastructure remains the inheritance of an earlier era of suburban commercial design. Township officials have not announced a follow-up traffic study; residents in adjacent neighborhoods are likely to look closely at evening volumes through the early summer. The opening also raises the question of whether the township's Vision for Wayne master-plan focus, intensely concentrated on the historic business district along Lancaster Avenue, has the bandwidth to also address the King of Prussia Road sub-economy now emerging around it.
