Five Guys as a whole is not closing, just certain franchises that are not succeeding in certain markets. While some call them Mediocre Five Guys represents the best of the Fast Food burger chains.
Juicy patties, delicious fries, topping galore. Many people complaining are so used to mediocre Mickey D's food they have become complicit and get upset when a Burger chain offers A+ quality burgers but the price if Hefty.
Quality doesn't come cheap guys... You want cr-p go to Mickey D's buy a cheeseburger for $1.00, you want quality great tasting hamburgers you pay $6.00-$8.00 at 5 guys (depending on store location, but price is average across US).
Stop sharing fake messages, 5 guys remains strong and viable, weaker markets where incomes are not strong, thus making the ability to splurge on a 5 guys meals, will make those stores struggle.
