I recently visited gokul chaat in koti and had an awesome experience.I ate samosa chat it was very tasty and the service was also very quick. They also provide other fast foods like cutlet chaat, samosas, dahi kachoris etc.
The only thing I didnt like was the card were not acceted over there and with problems in ATMs nowadys.Swipe machines are neccessary for every shops.Highly recommend this chaat centre.
