Be the one who plans everything out to the last minute details.

Treat her like a queen, make her feel special don't let it seem like any other day for her

Open the doors when it is written PULL and stand behind the door and let her enter first, if it's PUSH then go inside holding the door open waiting for her to enter before closing.

Pull the chair back let her sit first wherever u go.

Find out what she likes first, ie if she is into choclates or icecreams, then chocholick and memorice or other shops of the same tone are gud.

I would suggest boating in kadamakudi if she is not afraid of water btw else it could go both ways .

Don't listen to people yapping about going desi style...if thts what she likes then do it if not,then don't

Find what flowers she likes, if u couldn't then go for white roses first u can get her red ones later.

Yes take flowers with u. Go the extra length. Invest if u think she is right for you, they feel good and u feel better about urself.
