I had some really great take-out from Namskar earlier this year. In fact, the food smelled so good that I sped home to eat it... and got a photo radar ticket in the mail a few weeks later!
I ordered my standard vegetarian takeout order: vegetable samosas, palak paneer, aloo gobhi and dal masoor. Oh, and some rice of course! I had a friend over for dinner that night and then I ate the rest of the food as leftovers: these dishes provided enough food for four large meals. Everything was nicely seasoned, fresh-tasting (and fresh-looking!) and just plain good. I will definitely continue getting take-out from Namskar in the future.
You can also eat at Namskar, and I'm sure they have a buffet (maybe at lunch?). My one annoyance would be that their website opens with a painfully slow welcome video, with no option to skip it, so I'm not going to bother checking to find out details about eating in. You can visit their website yourself to find out!
