What could I do for my boyfriend on our date?

My boyfriend and I have been dating for almost 3 years so it isn't pre-date jitters or anything but a lot of hard times have fallen upon us and we haven't actually went out lately. I was thinking since we always eat out on dates that I could pack some food and take it out to our city lake and have a picnic. Then we could go catch a movie later on. Any other suggestions? Would it be better just to eat out somewhere?
