Visiting soon for Valentines Day, any suggestions?

I will be visiting Denver feb 11 through the 16th. My girlfriend is flying in on the 13th so that we can spend Valentines Day together. We are 20s/30s years old. l'a like to make it a special trip of course and have somewhat of an itinerary for us. Can some locals make some suggestions of things we can do that aren't the typical tourist results i'd find if I searched? I'd like to get her some nice flowers to have waiting at our airbnb. A nice dinner would be great as well. And any places with good vibes for us to go after a nice dinner on v-day as well would be nice. Any events that weekend like comedy shows or other things going on worth checking out? Thanks!
