We were in Mountain View yesterday and stopped and had Pad Thai at Tung Kee. I've often had wonderful soup dishes there. There is a wide variety to choose from in the Southbay and also Daly City. What about San Mateo to San Carlos? I'd love to find a Tung Kee "like" restaurant that specializes in different soups and noodles at very reasonable prices. Most items at Tung Kee are $4-5.
It seems like there is a void in this area but maybe you have discovered some restaurants that you could share.
