I recently visited Royal Skill Food and had 2 pieces of Plain Idli Sambhar - the quality was really good, very soft and they got it right with the sambhar too. An excellent combination, highly recommended.
Royal skill food is a great place to get South Indian food. My favorite dish is their Masala Idli Sambar which comes with 2 pieces. It's flavorful and definitely worth the price. Great place to grab a healthy and delicious meal!
