This cake shop is at prabhat centre I have been there many times for cakes and pastries my 3 year old son is huge fan of monginies pastries now coming to the point:
Cake quality is good but you cannot compare with international brands.
Pastries and other bakery items price are reasonable not very expensive.
You will find that 2 uncles ( owners) rude sometime but they give you excellent service most of the times.
Now last and important thing they dont do home delivery. Most of the times they deny home delivery for half kg cake saying aadmi nahi hai, and if you order 1 kg or above they accept ths delivery in CBD only.
