Interior design & layout. On the heals of the Luton & Bromley openings we have just opened Quiznos in The Treaty Centre, Hounslow. This is a special site as it is the first to have a shared seating arrangement in a food court, so our design & fit out was just for the front & back counter as well as the kitchen. The site stands well next to its counterparts with Burger King not too far from it.
