You have to pay a toll to get into the place, then you buy food to offer as prasad to Krishna. The temple guys attempt to squirrel away the prasad but my lovely guide says here, give it back. The racket being that the box of prasad is then re-sold outside the temple grounds.
Dakor is quite a delightful place, with a large tank full of turtles, a scale with a mountain of nose rings on one side, that was weighed against some fat tyrant or other, and a Lakshmi shrine where you can peek into her bedroom. ♥
