I know this is not particularly good for dating. But recently I thought that it would be a great idea to take some complicated cooking class together. Also learning a foreign language is fun, we are now learning Italian for our big trip. But I don't think it's a good idea to do any of these with someone you are just starting to date.
Go to Las Vegas and gamble together, that's a thrill. And I am a sucker for action parks (Coney Island here), a juicy sausage and pepper sandwich and some non-rollercoaster rides. Not long ago I went to play miniature golf and I did some batting in the batting cages, it was so much fun! We also have tennis courts all over the place, I love playing tennis. Pool and bowling is a blast, although I personally prefer pool over bowling, the ball gets too heavy after a while.
I really liked the brunch at a jazz joint and bowling after, it a was fun packed day. Ooooh, art museum or a natural history museum any day. Love the aquarium too. Ok, sorry this is not about me.
