The Hotel Morelia offers spacious rooms with shared bathroom from $125 Pesos in a safe location. A pleasant place to stay cheap in Tijuana, right in the midst of it all, but reasonably quiet. Only stay here if you need budget accommodations within the vicinity of Av Revolución and do not bring any valuables. Also note that the hotel does not require a deposit for the key, so if the clerk asks for a deposit, he is looking to pocket extra money from you. Do not bring any valuables, because the hotel clerk may steal it from you.
A newer hotel at the upper end of mid-range pricing, located on 8th Street just west of Ave. Revolucion. It has a very good restaurant and bar, comfortable rooms with plasma TVs and free WiFi, and free admission to the dance club "Las Pulgas" which is right around the corner. The staff is very polite and helpful, and most speak decent English. You can get a discount of MX$100 to $150 pesos per night on your room by booking online.
Reputedly the birthplace of the famous Caesar's salad, in 1924. It is still served there according to its original recipe, mixed and served at your table in accordance to tradition. It has been recently remodeled in October 2010 with all decoration still similar to the original of the 1930's.
Unpretentious, non-touristy quasi-Spanish taberna that has been open since 1947. Filled with bullfighting memorabilia, it is a slice of Spain in the heart of Tijuana. Their sangría and tapas have a good reputation.
The Hotel Nelson is reasonably-priced and clean, and has a bar as well as a restaurant downstairs. The major drawback would be traffic noise from the myriad bars and clubs along this tourist-oriented street.
For about 8 blocks, Revolucion is lined with shops, bars, and restaurants, many aimed at tourists. This is what most day-trippers to Tijuana experience, and it should go without saying that Revolucion is not representative of Tijuana and certainly not of Mexico.
Constitucion Avenue, one block west of Revolucion, is a busy downtown street but with none of the touristy nonsense. It is probably worth walking along here just to get a more authentic picture of Tijuana. Visitors should be careful (or aware) of walking too far north on this street, best not to go below Juarez (Segunda) as it will abruptly lead you into the “red light” district.
