Guess where I'm eating this burger and win a $25 gift certificate to Momos Ouzaria Taverna (630 North and South Boulevard, University City; 314-863-3511).
Rules: To be eligible, you must leave a valid e-mail address, Twitter handle or Facebook profile URL in the comment-entry field. One guess per e-mail address. Employees of the restaurant in question and Riverfront Times are not eligible.
Update: (Friday, November 2, 10:15 a.m.) Congrats to Widmer, who was the first to identify this as a burger from the Shack PubGrub (3818 Laclede Avenue; 314-533-7000).
Hint #1: I'm within the City of St. Louis limits.
Hint #2: The restaurant opened this year.
