Goodtime Burgers offers $5 burgers every Wednesday with any drink purchase.
The burger changes on a weekly basis - check out their Facebook page for which $5 burger is on for that Wednesday.
Note that these are for the single patty burgers. It's an extra $4 for a double patty.
Pair it up with Happy Hour during Monday to Fridays 4-6pm where all house beers and house wines are only $4 according to this website:

Darn, I forgot about this - in my suburb. Burgers are good though the place itself could use a clean (sticky tables), and the burger itself can take a long time to arrive esp on Wed when they run this promotion.
