Pizza

Today's Challenge will test your individual skills of observation and deduction:
I had to try seven pizza places before I found one with free delivery...
You make the leap that you need to count the pieces of pepperoni in each slice, and you get (clockwise from the top): 59263141.
You then realize that these make up the numbers of pi (pie from the photo). Trying stl.la/pi doesn’t work, so from the clue (seven places), you try pi to the 7th decimal place: 3.1415926, which is your answer:
stl.la/3.1415926
