Visited the Japanese Garden in Washington Park. It's a beautiful place and well worth a visit. We went on a Friday afternoon and it was a little crowded. I'd recommend going during the week or going earlier in the day so it is a little more peaceful. Also, the park is fairly close to downtown, also houses the zoo and the rose garden and seems to be a very popular destination. So, I suspect parking is an issue particularly on weekends. We took the light rail (Max) and then the Washington Park loop bus and found that to be pretty convenient.
