Super Duper Burgers is celebrating the 9th Annual Super Duper Day on Monday, April 29th. There are two pretty cool ways they’re giving back to say thank you to their customers as part of the celebration. From 5pm to 8pm, any teacher with a valid school ID will receive a free Mini Burgers or Veggie Burgers at every Super Duper, except for SFO and Oracle Park. Additionally, for the early bird, as they’ve done in previous years, the first 100 guests in line will receive free Mini Burgers (4oz patty) or Veggie Burgers.
Here are the locations in San Francisco below.
