I agree, Five Guys is hardly different in price from other places. A Five Guys combo is about the same price as a large sized McDonald’s combo. The portions at Five Guys are huge (particularly the fries).
I’ll take a place like Five Guys any day over the meat paste from McDonald’s.
Yep, Five Guys, Burger Fi, and some other chains are a much better value, a little more money, but a lot more freshness and some level of hybrid service also. Those who compare them to BK or McDonalds (and I like BK too) are making a flawed comparison. But as you say, the money is not that much difference anyway.
