A beautiful aquarium. The in-house app didn't function very well. Bring your own food, perhaps?

We arrived at 1130 on a Monday in February. The aquarium was not crowded (no cruise ship in the harbour). You pay at a window outside (or online, but there seems to be no savings to do it online) 27 Euros per adult, so it is not inexpensive. Once inside, you can download their wifi (probably a good idea due to the thick concrete walls) and they have an app that is supposed to: track your movements; knowing where you are giving you additional info and narrative in English; additional photos and a kids game (maybe a hunt to see if the kids find all the stuff?) This is free, included in the admission which is good since it was frail; didn't always know where you were; and the kids game never seemed to be working. Nevertheless, there are digital touch screen information boards at each exhibit in 3 languages, giving you information. The exhibits themselves were amazing. A North American tourists we saw fish from Africa, Asia and Australia that we had never seen before. Spotless clean tanks. Interesting layout as you walk along a route through the adjoining tanks. Well done and worth the price of admission. Two restaurants on site: Nemo's and Nestor's. Don't know about Nemo's but Nestor doesn't serve sandwiches or main food types after 1200 noon??? (Just chips/ice cream) You don't reach Nestor until about 1:30 or 2 hours into your walk, so this isn't at all helpful. Bring something to eat if you think you might get hungry!
