In this situation the best way to get her extremely excited what you should do is seed, and if you don't know what seeding is, it's when you build up her anticipation for the date by indiscreetly sliding in statements to get her hyped, so if you were going to some coffee shop that isn't Starbucks, you'd say something like "(the place your going to take her)'s Mocha's so good it makes heaven look like trash, but maybe I shouldn't take you here, I don't want to make someone else an addict.

" or something along those lines, and the same applies to wherever you're taking her, take a small detail about it and amplify it to the point that it's as exciting as meeting Denzel Washington. The more you do it, the more excited she'll be... Good luck friend
