NLA Bookplate and Paperplate Cafes have reopened. They closed in mid November, due to the commercial provider ceasing trade. The Wombok salad is back on (and better than ever) at the Paperplate Café, the less formal of the two, downstairs opposite the map room.
I have only had a coffee so far at the more formal Bookplate Café upstairs next to the NLA foyer (and with stained glass windows). The new management appear to have avoided the mistake of messing with the menu, but have done some redecorating. There are two large sets of dark wood bookcases, one full of antiques, such as typewriters, an old voltmeter and a plug-board from an analogue computer. If visiting Canberra, this is a good spot to stop, rest and eat. One catch is that the Federal government is now charging for parking in the parliamentary triangle area, so visitors also have to pay for parking when visiting the university (I avoided this by catching the Number 3 bus).
