Yeah, I can't speak to how authentic it would be, but there are a couple of Indian places here that multiple people have recommended. But I would know the difference lol. Austin has a ton of good food, so it wouldn't surprise me to find some good Indian. And there are a fair amount of Indians here.
No problem with all the spices and what not, my wife cooks a lot of different stuff and keeps a pretty diverse pantry with stuff like that. She helps keep my palate spectrum wide
There are some good markets here though as far as Asian/Indian, the wife loves those shops.
