You can win a $15 gift certificate to Taqueria la Pasadita, and all you have to do is guess where we ate this sandwich.
Rules: To be eligible, you must leave a valid e-mail address (or 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: [Monday, 8.15, 4:55 p.m.] Congrats to commenter Christopher Harrison, who correctly guessed that our sandwich came from Shameless Grounds.
