I'm assuming we arrived at a bad time. The place was empty but for one young fellow watching TV. When we got his attention, he brought the menus. We studied them, but fruitlessly: After we gave our order, we were told that nothing was available but drinks, as the cook was out. So, we asked for carrot juices, but what eventually came back to us was wet carrot pulp in a glass.
So, the kindest thing we can say is this: Maybe it's OK when the cook is actually there.
A respectful suggestion to the owners: If nobody who knows how to prepare the drinks and meals is there, it probably would be better to hang the "closed" sign until they get back.
