What people say
S3 Coffee Bar on Mission Gorge Road is a must-visit for coffee lovers in San Diego. This coffee shop has been serving up delicious drinks for three years now, and they continue to impress with their innovative and refreshing beverages. Their recent spring drink offerings were a hit among customers, and we can see why! S3 Coffee Bar also supports women in the coffee industry by sourcing their new beans from an all-women's coffee farm in Veracruz. It's great to see a business that values diversity and inclusivity. Additionally, their Valentine's Day flower pop-up was a lovely touch for those looking to treat their loved ones with both coffee and flowers. Overall, S3 Coffee Bar is a fantastic spot to grab a cup of joe and support a local business that cares about its community.
