Four things to do around Atlanta on Monday, Mar. 21:

1. FEATURED
It's a great day to take a self-guided outdoor tour to some of Georgia's most historic destinations. Put your explorer cap on and enjoy the adventure. [Spring is officially in the air. Which spring festival are you most looking forward to? Cast your vote here for our next Best of Atlanta poll.]

2. FREE & CHEAP
Merc Mondays launches today at The Mercury, where you can pull up a chair at their extensive 35-seat bar or mid-century lounge and enjoy half priced cocktails all day long from their classic cocktail menu. [If you are a little less polished up this evening, then you should check out Atlanta's five most iconic dive bars.] 

3. FOOD
It's finally here -- a chocolate tasting and behind the scenes peek into Xocolatl's micro-factory. Satisfy that sweet tooth and chocolate curiosity all at once. [Need something savory to balance all of that sugar? See who won our Best of Atlanta appetizer poll last week.]

4. FAMILY-FRIENDLY
The Atlanta Science Festival is in full swing this week, and today your family can participate in Maker Monday at various locations around the city. Create whatever you can dream up with tools, materials and equipment supplied by Maker Spaces. [Cultivate their love of science by enrolling your kid in one of metro Atlanta's best summer camps for kids who love science, history and reading.]
