According to market research firm Technomic Inc, Five Guys Burgers and Fries was the fastest-growing restaurant chain in 2010.
The estimate of 5G's sales - $625 mil - was not near the top, but their 38% increase in sales, and 35% increase in stores, was. The second fastest grower was Jimmy John's, with 22% and 20%.
Although this growth seems almost designed to prevent me from my epic goal of visiting every single guysguysguysguysguys, I congratulate them. I guess.
