I've always been kind of torn between the Old Tea House and Tapioca Express. I keep on coming back to the Old Tea House for the food. Even after three years, and even when we revisit Davis, we can't get past ordering the same dish! Crispy noodles with beef. AuugghhH! Heaven! That's all I can say. You need to try it out for yourself.
There are usually movies on TV. However, they're usually in Chinese. I don't speak a word, but I can sometimes follow along. Anyhow it's pretty entertaining to see men leap buildings like it's nothing.
Then of course, there are the tapioca drinks. If you've never tried them, be ready for an interesting experience. It grows on you.
