so romantic and definitely a once in a lifetime experience.  if you feel like splurging, make a reservation well in advance (months... plural) for a sunset dinner.  at 376 feet up within the eiffel tower, you will be escorted up a private elevator to the restaurant where they will ready to wait on you hand and foot.  if you order the prix fixe meal, be prepared to dine for a long time (and pay big bucks) -- but so worth it!  be sure you finish up with dinner in time to make the last elevator ride up to the top of the tower.  we were waiting to go up there our entire trip and missed it.  a real bummer.... sigh.  next time!  at least i got to have dessert.
