We're going to be spending some time in the Bay Area at the end of Sept. We'll be in San Jose for 3 days. I want to attend a concert at Mountain Winery and go to the Tech Museum. We will go to San Francisco and fly home from there. Any recommendations for getting to Mountain Winery? Also hotels and good ethnic restaurants.
There have been a couple of shows at Saratoga Mountain Winery, once very recently, that I wanted to attend, but I didn't partially because of the cost, but also because of the traffic (it's about an hour from our house). I actually asked a friend about it recently, because she mentioned going once, and she couldn't recall the traffic being bad going in, just coming out.
But I think your question is "how do I get there?" For that, your options are private car, or the private shuttle ([original link]). If you're not planning on renting a car already, then I would just suggest taking the shuttle. The locations in Cupertino are probably easier to reach by public transit, but it depends on where you're staying. I wouldn't necessarily recommend a taxi or Uber because it'll be pretty expensive.
For hotels, it mostly depends on your budget and dates. Both SF and SJ can be really expensive during the week or during major events. For instance, Dreamforce is coming up in a couple of weeks, and that basically fills up the whole of San Francisco and a lot of Silicon Valley. Hopefully you're not coming then.
For ethnic restaurants, SF is more varied, but I think San Jose is better overall. If you like Vietnamese, Japanese, Cambodian, Malay/Singaporean, Indonesian or Filipino, then San Jose has what you want. The problem will be reaching these places without a car, if you're not renting one. There are some very good Indian and Pakistani restaurants just outside of San Jose, but most require a car. San Jose itself has excellent Vietnamese food, especially around the area known as "Little Saigon," along Story just west of US 101.
I've had really good Chinese food in San Francisco, but it was well out in the more residential areas. There is a very good ramen place near Union Square, though it is well known and often has a wait. So, for SF, I think it depends on what you want for ethnic food.
Hope that helps some.
Looking at the Mtn Winery location at Saratoga I would guess your best bet would be UBER. However, after looking at the shuttle if the times and pickup locations work for you then it is probably your best deal. Even their point to point might work.
The SF/San Jose area is culturally diverse, so there are wonderful ethnic restaurants at a range of price points. There's a very good new Chinese restaurant in SF's Chinatown, Mister Jiu's. I am in the Silicon Valley area periodically on business, and I've taken a shuttle to Mountain Winery that picks stops in front of Big Basin Burger and the Inn at Saratoga in Saratoga. It also makes stops in Cupertino. This is a really easy, inexpensive way to get to Mountain Winery if you don't want to rent a car. I also like to try to go to SF for an extra day or two and fly home from there. It's easy to take a cab or UBER to the light rail stop, CalTrain. It takes about an hour and a half to get there, and it's fun, but I love trains!
