Why did we dine here? – Lers Ros is a popular Thai restaurant in San Francisco with a newly opened location in Hayes valley. We have never dined here previously, so it was a good excuse to check out the new location. Lers Ros means “excellent taste of the food” in Sanskrit. Tom Silargorn is the owner and chef. Michael Bauer has this restaurant in his top 100 Bay Area restaurants for 2012. This review is the culmination of two visits. The restaurant is extremely noisy during peek times and also cramped. Last visit was in 2017.
