We had lunch there yesterday, as management has been nagging me to go there since it opened.
It is called Volcano, which put me off a little as we have used Volcano in the White Centre on a couple of occasions, and in my humble opinion it is the most overrated establishment in Caleta, however, I digress it took us a couple of minutes to find it as although it is signposted from the outside one you enter the museum, it isn't. It is actually immediately to your right and behind you, has seating inside for about 20/30 and a terrace which seats circa 70/80 with a very nice view over the salt beds and to the sea, we arrived at 12:15 but it does not open until 12:30 so we were very politely asked if we wanted to wait and have a look around while we waited, which we did. There were only two other customers there while we were there, and the staff outnumbered customers 2/1. There is a decent mix on the menu which I assume changes frequently as they are on clipboards and not set in fancy holders, there is also a selection of Fish of the day which the waiters/ waitresses have on a different clipboard, they served us with a sample of crisp bread with truffle butter, which actually tasted of truffle while we waited for our starter we had a starter to share which was is fried potatoes and chorizo topped with poached eggs, { The Canarians have a name for it as we have had it in two other places, but I cannot recall what it is } but it was very good, followed one of the selections of the fish of the day menu again it did not have a name but was the only fish choice that was not served with rice, but Canarian potatoes, both the fish and the acompaninebts were excellent, the lady who served us spoke excellent English but you could detect an accent and when I enquired it turned out she has German parents but was brought up on The Island, very polite and very jovial, a bit off putting with her German heritage
A starter to share the fish for two and two bottles of water plus a tip 60€ excellent value I think probably not the cheapest but not the most expensive either, would we go back? Without a shadow of a doubt, and probably within the next week, and believe me I am a hard man to please when it comes to restaurants.
