Spring has officially sprung, and we hope you enjoyed your weekend. Yes, we wish we were outside today, too. How about some free grub to soften the blow of a new work week? If you think you know where we got this delicious mushroom burger, let us know in the comments.
UPDATE: Commenter pyth got it right: we were ate Five Star Burgers (8125 Maryland Avenue, Clayton; 314-720-4350).
Simply study the photo and leave your best guess in the comments. If you're the first correct answer, we'll give you $25 to to Cyrano's (603 East Lockwood Avenue, Webster Groves; 314-963-3232).
