Sushi places in Hyderabad

Hey guys, so my sister is here from the North. She has never had any sushi. We went to Taro, there she tried Prawn Tempura sushi and has apparently fallen in love with it. Now the 4 piece sushi costed 700 INR. I mean to ask, is there a place that gives cheaper (but still good quality) sushi so that she (and I and fam) can have lots of sushi without breaking the bank. Any other place that gives out good sushi on a budget? TIA!
