Want the scoop on San Francisco's most talked-about local spots?

We took a data-driven look at the question, using Yelp to uncover which restaurants have been in the spotlight this month.

To find out who made the list, we looked at San Francisco businesses on Yelp by category and counted how many reviews each received. Rather than compare them based on number of reviews alone, we calculated a percentage increase in reviews over the past month, and tracked businesses that consistently increased their volume of reviews to identify statistically significant outliers compared to past performance.

Read on to see which spots are closing out the summer strong.

Bac Lieu Restaurant

Open since June, this Vietnamese restaurant is trending compared to other businesses categorized as "Vietnamese" on Yelp.

Citywide, Vietnamese spots saw a median 1% increase in new reviews over the past month, but Bac Lieu Restaurant saw an 80.6% increase, maintaining a healthy 4.5-star rating throughout.

Located at 3216 Mission St. in Bernal Heights, Bac Lieu Restaurant offers a full menu of Vietnamese favorites, like bun noodle bowls, pho, spring rolls and rice platters with meat and seafood. The menu also includes a number of chef's recommendations, such as quail, seafood noodle soup, vegetarian pho and bánh khot — crispy mini shrimp pancakes. Explore the full menu here.
