As old fashioned it sounds - dinner and a movie, or movie and dinner or movie and drinks/coffee, or any comination of those, are my idea of a great first date. I always like having the opportunity to talk after a movie to discusss our favorite parts etc. pure romantic movies are out of the question. Comedies, Thrillers, Action, some Drama, and of course HORROR movies would be what we'd be seeing - yes, we coiuld see all in one day, I've done it before and I can do it again!)
For Dinner, I like italian for a first date - there is usually something for everyones taste, and the last thing I'd want to is leave a bad taste in your mouth while watching the movie.
I'm not one to buy things like flowers and candy, except for movie candy (sour gummie worms are my favorite), but I certainly don't mind paying for the show and the food.
