Consistently rated one of the best food trucks in San Francisco, The Chairman is a culinary delight! They have a small menu of steamed and baked buns with exotic fillings (including a great vegetarian offering), but everything is unique, well-prepared, and fresh.
There is always a line but worth the wait. You can find them in a different spot every day, so if you are visiting San Francisco plan a trip around checking these guys out!
