Like Indian from India? Why should they be treated any differently?...
Are you an Indian Guy or not?
If you are an Indian guy you need a totally different approach angle.
But if you are not Indian, here is what you can do. I guarantee you this WILL work:-
Ask questions about her Country? If you know any stereotypes .. ask them if its true. Eg:- Do you guys put like 200 spices in your foods?. I like spicy food, but you guys go overboard. Laugh and smile throughout the conversation, to make it not sound personal. Ask her (first) name and try to pronounce it. It is very likely you will get it wrong the first time. She will correct you. Then laugh and ask them their last name. Repeat. Say :"You guys have the toughest name, but I like the sound of your names". Trust me, although this might sound rude, they will love to talk about it and from then on.. you can go ahead with your normal conversation as you would with any other women.
For closing, you can say, tell me some good Indian places to eat. It has to spicy food though. etc..you can ask her out on a date etc.
Note:- very few Indian girls drink alchohol, so asking out to a bar/club might not work out well.
Honestly I've yet to meet an Indian woman who wasn't in an arranged marriage so be sure to ask. She may have been engaged 15 years ago by her parents to someone for an expensive dowry and they will not want their investment soiled.
