I was in Tijuana a short time back. There is some interesting shopping on Avenida Revolucion, you could spend and hour or so there. The cultural center is interesting. There is a Hard Rock Cafe and two Bull Fighting Rings if you are into that. I would not hang around after dark. I agree on taking a trip to Rosarita Beach a little south. I was able to get a taxi for $25 each way.
