Fun Stuff
I usually find time to shop maybe a couple times a semester. When the urge hits me, I find myself heading to Emeryville's Bay Street (you can catch the F from Bancroft going toward SF and get off at Bay Street). I like Banana Republic, B&N, Gap, and the cute, pink bakery shop they have. And, I have a car here, so it makes going to Emeryville all the more tempting. However, I don't like to drive to SF. It makes me very nervous! I'm from Orange County, where one lane of a road can really fit two cars side-by-side. But anywho, I do enjoy shopping on Market. You can easily catch the BART, although I would recommend waiting a bit, considering the recent freeway loss will increase public transportation use.
Unless, however, you don't mind being packed into a subway with many people. There used to be a Gap that I liked right on Bancroft, but I think now it is being turned into a Walgreens.
As far as places to eat, I wrote an entry last semester on my favorite places. I also bought the Chowhound's Guide to the Bay Area from Borders. Check it out! I think it's worth it if you want to find all the secret spots around here.
If you enjoy tennis, you can call (510) 642-8345 to make court reservations. I strongly recommend it if you don't want to be kicked off by other people. I would suggest the courts on Channing to play on, as those are used by the women's Cal team and are very nice. The Bancroft courts are decent, and if you are going for more social tennis, that is a good place to be.
I would suggest checking out the Guide to the Good Life in Berkeley for alternative things to do. However, don't feel like you have to do most of the activities listed, because you do take classes! Hike up to the Big C if you haven't already (I will soon, I promise) and visit the Rose Garden down on Euclid. Have fun!
