Took my cousin out for lunch at Golden Dragon@Vasant Vihar over the weekend. Pretty okay place, with low music, no loud mutterings, and the kind where you can have a decent conversation without having to literally vomit into each other's ears. And best part, they have happy hours, 3:30 to 7:30pm. Yupppiee, so dropped the idea of eating, instantly.
2 non veg starters and 4 bottles of beer (2 got multiplied into 4 because of buy one, get one free offer) for Rs. 1000 (includes taxes and non-irritating waiters who wouldn't come to your table after every 10 min - not the typical restaurant scene here).
Golden Dragon at Panchsheel and Gurgaon are also good, might be at a slightly higher side, but food they serve is good.
