Guests of sports bar Taco Mac in Sandy Springs might not know that there's a secret beer heaven at their feet. Formerly known as The Fred Bar, named for beverage manager Fred Crudder, it is only available to members of Taco Mac's Brewniversity and their guests. It's now called the Georgia Chapter Room. Signing up for the program is free, but you must be at the "pledge" level, meaning you've sampled at least seven of their beers. To enter, go down to the loading dock area where the door on the left has a red button. Press the button, and an employee will let you in after verifying your credentials. The decor is swankier than upstairs, with leather chairs and curtains. The entire menu is available on an iPad placed on your table. The secret locale is also a step above when it comes to both food and drinks. The beer selection includes aged, rare, and lesser-known brews curated by the knowledgable staff. This is the place to splurge, as the staff can recommend something you will enjoy.
