Lisbon Gulbenkian museum under renovation, but "highlights" exhibit open at the Foundation building

I saw some posts not speaking too highly of the Gulbenkian museum in Lisbon, but I want to see what I can. It is normally on the RS tour, but this year it is under renovation. I accidentally found out there is a smaller exhibit available in the Foundation building, across the garden. There are guided tours in English on Mondays. I hope this helps someone.
