Budapest and its cakes

Hello, I will be travelling to Hungary for 3 full days (and one morning). I plan to spend 2 full days in Budapest (Sunday and Monday) and on the 3rd day I plan to explore Szentendre.

I was planning to go to Ruszwurm Cukrászda to taste Dobostorta, Esterházy torta and Krémes (Ruszwurm torta), but now it's shown as temporarily closed and by doing some research the future doesn't look that bright and it surely won't be open again that soon.

Another potentional place Auguszt Cukrászda is closed on the days of my visit. Any suggestions that aren't just meant for tourists and preferably a place, where I could get all (or at least 2) of them at once? How good is Szamos Gourmet Ház, at least Dobostorta and Esterházy torta can be found there.

And where to even find Krémes (Ruszwurm torta)? Is it even being made in any other place than Ruszwurm Cukrászda?

Thanks in advance!
