The coffee shop – which is to be located at 1 King Street – is rumoured to open at the end of the week.
This morning (Thursday) a sign with the opening hours has gone in the window.
Starbucks will be open from 7am to 7pm from Monday to Friday.
On Saturdays and Sundays it will be open from 8am to 6pm.
Staff have today been busily putting the finishing touches to the interior of the building.
The tills, screens, seating areas and other interior features also seem complete.
The cafe will also have free wifi.
A planning application to put up signage was submitted by Dransfield Properties – owners of the Five Valleys Shopping Centre – in the summer.
Originally the developers had intended that the King Street unit would be a pharmacy however they said that no pharmacy in the town centre had been willing to relocate.
The new coffee shop will be next to the new medical centre which is planned to open this year.
