Do you use Yelp? I have the iphone app and am newly obsessed with it.
Lately I've been using it to make all my dining, shopping, and sightseeing decisions. So far I haven't been disappointed, and I realllly love the 'check-in' feature that allows me to track where I've been and unlock deals.
G and I recently went to Cape Cod, and we used Yelp to create a barhopping adventure, and pick some nice places to eat at (and the favorite dishes).
G and I also started up a battle of checking into the most places, and checking in first when we are together :)
If you want to be my Yelp friend, you can add me here!
