The Pepys Visitor Centre
I know, I know. Who apart from rank tourists goes to a visitors’ centre?
Well, me, actually. This one is a model for how visitors’ centres should be. The people behind the desk know what they’re talking about, the selection of local publications both for sale and for free is excellent, and the layout is clear and uncluttered. Nobody bothers you if you’re browsing the well-kept, up to date “what’s on” racks of leaflets and flyers but they’re helpful if you actually want to know anything.
If you go into the main part of the building there’s the Old Royal Naval College gift shop which is not half bad, a small group of genuinely interesting displays and a reasonable tourist coffee shop. The loos are free and clean. I heartily recommend that you make it your first stop on arrival in town.
