Great idea...! Not only is this an (sort of) cozy setting, you get to find out what she likes and doesn't like, even if it's just for her "flavors of the moment." Opens up other possibilities with your new discoveries. Also, gives you a (hopefully) good memory which may be important in the future. Keep it simple...

Absolute decadence!!! Maybe have a light dinner as $30 of dessert can get you a LOT of chocolate! Alternatively, go a little fancy - get dressed up and head out into town to a classy restaurant for the dessert only date.

An all-time favorite! Romantic, decadent and oh so yummy! Love the idea of going to a fancy restaurant or a dessert-specialist restaurant for this one...

awesome idea , Romantic and Cheap.
