I often eat at Dana Choga - sector 50, as I live near that market. And though the taste of food is not bad, the customer service is very bad. It takes about 25 minutes even for small orders like one mini meal. Sometimes, they donot offer chutneys/free salad, and they never offer mouth freshener after dinner. Also though, there is seating available in the basement. it is often closed due to small staff. So there about only 3-4 tables on the ground floor.
