I will be spending a week at my mom's in early May. I haven't lived in the Bay Area for over 20 years now and all my old hangouts are pretty much gone. My mother lives in Livermore and while we will make a couple of trips to The City, I'd love to get a few recomendations that are closer to home. We are all pretty well omnivorous - no one in my family is afraid of food. I am looking for places within a 25-30 mile radius of Livermore, any type of food - though I must have Mexican and Vietnamese whenever I go to CA. We will probably do one or two upscale dinners, but for the most part I am thinking in terms of places where I can get great pho or tacos or dim sum or bibim bab. I also like Basque, Ethiopian, French, German, Japanese, as well. Thanks in advance.
