|Three sizes of inconsistent margarita specials.|
I've done the math for you below so that you won't have to bother, but it makes the most sense to order the smallest size margarita. The special has diminishing returns as you order the larger sized margs. The three different sizes of glasses and the advertisement for the special are pictured above. It's worth noting that they don't even tell you the size of the "Big Azz Margarita" - but I'm pretty certain that is a 22 oz glass. What a fucking scam.
$3 12 oz - 25 cents per ounce
$5 16 oz - 31 cents per ounce
$7 Big Azz margarita - 22 oz - 32 cents per ounce
My friend Paul provided the plausible explanation that even with this knowledge some folks might still be inclined to order the larger size so as to be considerate of the staff. I personally recommend that you just order two 12 oz margaritas at a time so that you are getting the best rate.
A few notes about Mad Mex, they offer half off all drafts during happy hour. Unlike several clown bars around town whose beer selection consists of 42 different IPAs, Mad Mex usually has at least a few different styles of beer to choose from.
I highly recommend the boneless chicken wings. Mad Mex is one of the few places in town that has a bonafide de-boned chicken wing as opposed to a sauced up chicken tender.
