Easton ashe playing today, it's amazing outside today. You need to find your spot and try the wines. We spent time at the Spotted Donkey and enjoyed a few cold beverages and yummy food.
El Pedregal is really trying to get traffic thru the plaza by bring great entertainment each and every Sunday in the Spring and Fall. The crowds are pleasant and always a nice breeze thru the plaza to enjoy the concert.
I recommend trying a few events and visiting the merchants in the plaza.
