(Instagram doesn’t show how many photos have been posted at a particular geotag, but there are over 66,000 images with the #museumoficecream hashtag.) All those grams have made the Museum of Ice Cream a coveted place to be: In New York, the $18 tickets to visit—300,000 in total—sold within five days of opening. At its San Francisco location, which opened this month, single tickets went up to $38. The entire six-month run sold out in less than 90 minutes.”
