You're correct - there was a Thai there at one point, as well as Fish Works which lasted about a year. It was actually a bingo hall back in the 70's!! Apparently Bills were offered a premium to leave and it's going to become Rosa's Thai Cafe - www.rosasthaicafe.com
they have a number of other restaurants.
Looks like Mori (yet another baby clothes shop!!) will be going into the old Hive Honey shop.
120 Northcote Road (the old Dandelion) is going to be taken by Smart Medical Clinics.
181 Northcote Road next to SDS is going to be a Skin Clinic performing beauty treatments including facials, Botox and Fillers.
The rumours about The Ivy have been circulating for years, first it was Starbucks, then Byron and now All Bar One. No idea if it will ever happen.
