Guess where I'm eating these tacos, and you could win a $25 gift certificate to the awesomely awesome Addie's Thai House (13341 Olive Boulevard, Chesterfield; 314-469-1660)
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.
Also: No one has correctly guessed last week's "Guess Where I'm Eating This Sandwich". That competition will remain open through Monday, October 22. One more clue: One of the existing guesses is very, very, very close -- though not necessarily in geographic terms -- to the correct answer.
Update: Congrats to oros.steve, who was the first to guess KimCheese (13435 Olive Boulevard, Chesterfield; 314-485-1408)
Hint #1: These tacos aren't from a taqueria.
