Rio - South Indian & Sri Lankan restaurant

This is the best Masala Dosa I have eaten on these shores. The dosa itself has the slightly sour fermented flavour that is the sign of a great batter. It was also crispy with a great filling. The sambar was perfect, the sambal spicy, and the coconut chutney delicious. A great authentic experience.

Authentic cuisine, very delicious and good service! Rio is an excellent choice for South Indian food, offering great value for money

If you're a pure vegetarian pls stay away. Vada tastes ok, kothuparotta is bad and Gobi Manchurian is the worst. My opinion maybe totally wrong for non veg. But for veg, this isn't the place.

Food has the authentic taste. Never tasted anything like this before. You need to let the chef know if you need less clarified butter and the chef cooked it perfectly as was requested.

Nice place for family dinner with authentic flavour dishes.

I 100% recommend it to people who love authentic curry food.

I ordered king prawn tandoori and paid £10. I got 5 regular small prawns and the taste was awful as well!! I got conned so please think twice before burning your money.

the mutton kothu is by far the best from all the south asian resturants around. They cater for all my parties. Thanks anna will come again

The serves was ok but it could improve and the food was nice but when the desert came my face dropped down
It’s not worth £3.50 (Vattalappam)

If you are Tamil speaking people, do go their and taste the food. First thing I was happy in this restaurant is, they brought glass of water and then asked what menu we need. Which you may not see in many restaurants in UK. It is located in Sutton, easy to identify. And I have to mention the owner, who also serves the food and drinks to us. He recommends the menu based on our taste and requirement. Highly recommended.
