On her blog, Nakarmiona Starecka describes Kubuś (translated from Polish) as follows:
There’s an incredibly good energy emanating from this place at 19 Marszałkowska Street. I’m not sure if it’s thanks to Kubuś’ decor, its luminosity, and fairy-tale charm, or the exceptionally friendly staff working in this open-to-look bakery. Kubuś timidly made its debut on Fat Thursday with a softly boiled egg-filled doughnut. (…) Kubuś is making quite a splash, and you can already sense that a spectacular success is in the making.
