The burger itself came out to around $5.20, the regular order of fries was $2.39, and the large iced tea was $1.89. Factor in California's 8.75% sales tax, and it makes sense.
The biggest thing that will keep me away from Five Guys is the price. I can get a Double-Double at IN-N-OUT for less than four bucks, and it is excellent. If I have a hankering for fries, however, Five Guys will get my business.
I think next time I'll try a hot dog (on your recommendation, SC.)
