Hey Arion - my wife and I are doing a month-long drive through the Southern states in January. We'll be in San Antonio the third week of January. Any recommendations for places to see, or restaurants to visit?
Well, this could be a simple answer but it isn't really because it depends on what you're interested in. Downtown, the River Walk is usually a "don't miss" place to visit and almost any restaurant on the river can be a good choice, again, depending on what you feel like indulging in. If you like Tex-Mex, Casa Rio is one of the oldest restaurants on the River Walk. I remembering taking the bus downtown in the 50s to eat there. It's still going strong!
The Institute of Texan Cultures in the Hemisfare grounds is also quite interesting, as is Hemisfare Tower at the top of which there's a revolving restaurant much like the Space Needle in Seattle. The Alamo is interesting but it can also be a disappointment. The Alamo is akin to a holy shrine for some Texans although it can be crowded which makes the experience less than ideal because it's a small building. It's right downtown and across the Alamo Plaza are typically touristy places like a wax museum, etc.
The Spanish Mission Trail south of the city is also quite interesting (the northern most mission is the Alamo). Our favorite is Mission San Jose which has undergone restoration since I first visited and the interior of the chapel is rather spectacular.
If you have time a drive some 70 miles northeast of San Antonio to the old German town of Fredericksburg is worth while. Good German beer, bakeries, and restaurants. It's also the site of the Admiral Chester Nimitz Museum of the Pacific War which is fascinating. If you go, plan on at least three hours to view all it has to offer. The first time I visited many years ago it was just the old Nimitz Hotel that housed the museum. Now it's almost an entire city block not including the annex a few blocks away.
No doubt there are other places worthy of mention but at the moment these are my suggestions. Enjoy your trip and best wishes for safe and enjoyable travel.
