Burger's Priest is finally this side of Yonge, and it's just as good as the original. For those first timers, be sure to get acquainted with the not-so-secret "secret" menu available on BP's website. The options here might cost you a little more than the advertised menu, but it certainly makes for a more gluttonous experience. I recommend Jarge-style on pretty much anything, it adds a tasty mustard sauce cooked into the patty as well as some delightful fried onions.
The shakes are good, albeit a little pricey. I'm a fan of the Riggs & Murtaugh, more for the cultural reference to a certain long running buddy-buddy cop series.
Now be warned, you will likely wait if you come anytime during the lunch rush, which kicks off just after 11:30 during the weekdays regardless of the weather. So be sure to come early, and if that's not a possibility, bring a book or some good conversation partners. One thing to keep in mind, it's well worth it, these are the best burgers I've had in the city.
The staff here are efficient and friendly and it's cash only, but an ABM is located by the washrooms, also several banks just around the corner.
It's a pilgrimage every burger lover should make and many thanks to the BP folks for making it that much easier for us western folks.
