R.D.
Instead of going somewhere expensive and fancy, maybe go somewhere you used to go on dates, even if that means the hot dog stand at the putt putt golf place :) For my anniversary, I plan on asking the hubs if we can go to this little hold in the wall bar, Metro Grill, because that's where we went for our official first date :)
If it's more in your nature to be FUN, not dressed to the 9's, go with it! Be YOU; you'll be much more comfortable :)
