This was our second visit to Cube, and I can definitely recommend it for any foodie. Chef Dario is famous in SA for pushing the envelope and he has excelled with this venture.
It's a bit daring for a restaurant to only offer a tasting menu, but looking at the waiting list shows that he has built a clientele. The restaurant space is small and intimate, and was full on both occasions.
It is extremely unusual for a restaurant to choose to forgo a liquor licence, as this is where most restaurants aim to make money, and I must say it is quite a pleasure to be able to BYO at an upmarket venue. As a result, Dario's focus is purely on the food, and the results speak for themselves from the first plate to the very end. As each course is served, one of the team of chefs (including Dario) comes over and explains the course, and the pride in their voice is evident.
This time we went was just after he had re-opened after the Christmas break, and he was offering a slightly pared down version (only 9 courses), since had hadn't had the time to prepare for their full menu, but it was just as delightful nonetheless. We started with a champagne cup (champagne jelly with mascarpone cheese and truffles), and continued with a home-smoked salmon sashimi. One of highlights was a micro salad served with olive oil icecream. The chef advised us to "mash it all together", which we did, and the result was the icecream became a very creamy salad dressing. The procession continued, at a rate of about 3 an hour, with seafood, foie gras (I tend not to be a liver fan, but this was delicious), duck served in a miso sauce and beef fillet served with a mulled wine jus. There were two dessert courses, butterscotch pancakes and chocolate and berries
There was however one sour note, in that one of the waiters seemed to lack basic courtesies. We repeatedly clashed with him as he persisted in leaning over my wife every time he tried to reach a bottle of wine that he had placed in an inaccessible place. On two occasions, after filling our water glasses, he put down the bottle right in front of me, instead of anywhere more logical.
My other criticism is that there is no visible signage outside the restaurant, which can make it quite difficult to find at night (feels like the "puerta cerrada" secret restaurants in Buenos Aires)
