I'll keep this short and sweet.
Almost intimidating for a first time visit, but worth it.
Here are a couple of tips so you don't look like a "rookie"
-Pop refills are free
-Any burger on the menu is a double patty
-A "Junior" burger, if requested, is only a single patty
-I hope you like lots of fries
-Make sure you know what you want BEFORE you get up to the counter to order so you don't hold up the line
-When they give you your receipt, there is a bold number on there. This is your order number. Make sure to pay attention to the guy yelling out the numbers for your order number.
-Burgers are very messy, especially if you ask for it "loaded" or "all the way"
Just a really interesting place to grab a bite to eat. Don't let the long lines turn you away. 25-30 people in line will only take about 7-15 min depending on orders... (Most people spend a longer time in Tim Horton's Drive thru, even though there is nobody waiting in line inside the store...)
**Just a side note: If you eat here, and by some miracle are still hungry afterwards, try eating a D.F.T.R. burger from Boogies Burgers.
