Going to San Antonio this weekend, staying on the Riverwalk. Looking for suggestions for places to eat on the way there and back. Which barbeque places are not too far off the route that we should not miss? Also in San Antonio, we are staying in a hotel on the Riverwalk. Are there any places that are musts ( Mexican or other ) either near the Riverwalk or near downtown? We will have our four year old son with us, so nothing too upscale, just looking for some great food. We will be there three days, so looking for breakfast, lunch and dinner recs. Thanks.
