There was one in London in Covent Garden market around the same era (perhaps a small chain, or perhaps just a similar name).
One image that I remember being particularly impressed by was a model of a radio telescope dish. You could look around the dish and see all the support gantry. The contrast between the smooth dish face and the structure on the other side made the 3D nature very dramatic.
On the counter they had a nice mirror illusion¹ of a floating "help" button - not a plate hologram but a really nice effect and you can still get these. They tend to be cheap plastic and dust and scratches affect them over time, but it's still a really nice effect if you've not seen it before.
