we have a TON of great Indian here in the area. unfortunately really none of it is in MY area, haha!
I will check this area out, I had no clue. But I can say that large Indian populations live in Richardson (75-Beltline, Arapaho-ish) and in Plano (Legacy/Spring Creek, Custer/Coit -ish) with a motherlode of great restaurants, grocers and Indian-centric businesses.
There's an Indian theater off 75 that shows Bollywood films and it's a lot of fun!
