Plans are moving forward to bring a 309-guest-room hotel to 17th & Chancellor Streets near Rittenhouse Square. The project, headed by Chancellor Hotel Associates would require demolition of Little Pete's diner which has occupied the location for 37 years. Since 2014, there have been on and off proposals for hotels at this site. Current plans for the new Hyatt Centric Hotel will be reviewed next month by the city's design-review board.
