Just over 18 months after opening, India restaurant on Main Street has closed, its owner said. Chef Prasad Chirnomula said he’s closing the downtown eatery which since April 2016 has served classic Indian cuisine and signature dishes, as well as five other locations due in part to “longer structural income versus debt issues.” He added that the restaurant itself did not fare well enough to support the considerable costs of operating it. “I love the town, I love the people there but if you can look at Main Street alone the whole street looks empty, everything is for lease,”Chirnomula said. “And I think I have been in New Canaan and I have seen the peak and Main Street was nice and busy—parking was always an issue, but I think right now almost no businesses are open on Main Street. There are not enough diners.
