Five Guys isn't a place you stop by everyday for lunch, mainly because you'd die before your tenth visit and you'll be broke.
The burgers are delicious if you like thin, crusted patties that are made to order on a pan top. They are not grilled and they are not thick. As far as I know they're unseasoned. Do yourself a favour and get the regular cheeseburger, not the mini wuss (unless you eat here everyday...).
The regular fries are good for two, but they're not as generous as the Five Guy's in America. The cajun fries are gross, but I know a few who love them...to each their own.
Drink are self-serve and free refills, so really you only have to get one cup and two straws if you're willing to compromise with your fine dining partner.
If you're allergic to peanuts, run away! The fries are fried in peanut oil and there are boxes of shelled peanuts there for customers to help themselves to.
I like my burger with grilled onion, mushrooms, pickles and lite ketchup (yes they do "lite" and can even go lite on lettuce). Not sure about this location but in general the jalapenos are fresh and not the pickled kind you get at a hot dog stand.
