Pizza Hut India — Clarification needed on the tax charged

I was at the cst, mumbai outlet today and on a bill of rs 1173 i was taxed rs 366 i. E. I paid a total of rs 1539. This comes out to be more than 30%. This basically means i have paid service tax (Rs 151) and vat both on the same amount. Additionally the stff took back the bill after i made the payment through my debit card and just handed me the transaction reciept. I was in a hurry and couldnt pursue the matter at the time but would like exactly have i been charged for.
