I recently visited Om Karnavati Fastfood and tried their butter vada pav - it was delicious! The vada was cooked perfectly and the bun was nicely toasted - just overall a great snack. Highly recommend giving it a try.
I recently tried Om Karnavati Fastfood's Cheese Vada Pav and it was really good! It was nicely spiced, full of flavor, and the cheese was fresh and melted. Definitely recommend!
