I went for breakfast as soon as it opened, and people were already seated outside. By the time I left, the place was packed.
The menu is available in English on the website so I already knew I wanted the vegan shakshuka. It was not quite what I expected, in that it was not spicy and didn't taste much like the original dish, but what I received was filling, delicious, and extremely well seasoned. It was made with a sauce of red bell pepper and tomato, with bits of pan-fried tofu, topped with spinach and mushrooms, and served with bread with olive oil. The presentation was beautiful as well.
The orange juice I ordered was rather watery and tasted like it came from a carton, which was a shame.
I am planning to return for breakfast again during my visit. It was by far one of the nicest breakfasts I had in Porto.
