Being from San Antonio, we would recommend Boudro's on the river for dinner. It is the perennial favorite of locals for the best Riverwalk Restaurant. On Presa Street downtown is Zinc. It is a bar, but they have a great small menu, a burger, salads, fabulous fries, flatbreads, and probably a special or two. You can sit outside if you like. It is really pretty out there and not a spot that a lot of people know about. A relatively new development in SA is the renovation of the Pearl Brewery. It has shops, restaurants, bars, and a Saturday am Farmer's Mkt. I love to go to it. Il Sogno is our favorite restaurant there, it is Italian. Mexican food on the Riverwalk can be touristy. La Margarita in El Mercado is pretty good. The Mexican Shrimp cocktails are quite good. Rosario's in Southtown is also good, and Traveler's World is close to it. The Guenther House at Pioneer Flour Mills is fun to visit. The home has been restored and worth a tour. They serve breakfast and lunch there, too. While in the area, visit the King William neighborhood, and in particular, the Steve's Home. Very interesting . The homes here were built by the German merchants who were responsible for much of the entrepreneurial spirit of the 19th spirit. A new home has recently opened down there and it has a lot of art work and several collections. Unfortunately, I don't know the name of it, but there will be pamphlets on the The King William Neighborhood, and they should tell about it. The folks at the Steve's Home will know about it as well. If you have any further questions, PM me and I will try to answer your questions. Hope you enjoy your visit.
