Pizza Pilgrims, the largely London-based brand, is set to open two more outlets this autumn as well as a new menu to coincide with the launch.
The company's City site - their first in the square mile - will open next door to Tower 42 on 1 October. Another site in the arches of London Bridge will open in November.
The City site will seat 135, and combine their standard menu with a significant wet offering through a large downstairs bar area which will screen football matches. It will be the first of their sites to offer a click and collect service in a bid to attract busy City workers on tight lunch breaks.
On their opening day the Pizza Pilgrims Piaggio Apé van will be parked outside the venue to offer free slices to passers by.
The October opening will also coincide with a new menu, featuring dishes like Bread Zeppelin - a garlic bread that inflates and balloons in the company's pizza ovens - and Pesto Datterini pizza made with yellow Datterini tomatoes and buffalo stracciatella.
In November the London Bridge site will open as a 104 cover restaurant beneath the area's train tracks with a 16-seater terrace.
In both sites half the proposed seating will be reserved for bookings while the other half will be open for walk-in customers.
The autumn expansion will build the Pizza Pilgrim empire to nine - including their one site outside of the M25 in Oxford.
