I've tried the marble cake
its filled with custard and coverd with chocolate
I liked it but i think its overpriced
the cake is enough for 5-6 ppl + some of the slices doesn't contain custard
update:
i got the mini size from the marble cake i believe it's much better than the big one
i also tried the pistachio chocolate it's delicious the cocoa itself is amazing
otherwise i didn't like the chocolate babka it has no flavor even the dough isn't fluffy enough
