Went on a fall morning in late October (outdoors area is free). Had some sun but cool. Not much blooming at this time in the outdoor garden, but still the hardscape and water features are very nice. Many plants lost their leaves by now. Enjoyed the circular walk around the grounds outdoors with the Thai Pavilion the highlight of course, in it's gold leaf spendor. We were very fortunate to come upon a Red-tailed Hawk at the Thai pavilion that was roosting on a bush nearby and cooperated for a number of photos before flying to a nearby bridge railing, then leaving the area entirely. Went on a weekday so not so crowded. It is relatively small, but very attractively laid out. There is no food for purchase available.
In the cold weather the tropical conservatory is a big plus. It costs $2 for adults to get in, but worth it. I came in from the cold to the humid environment so my camera lenses all fogged up immediately. Couldn't take photos for 15-20 minutes. I really enjoyed the tropical imported birds in the conservatory. They had Common Quail, Painted Quail, Orange-cheeked Waxbill (didn't see), Diamond Dove (didn't see) and Domesticated Canary. If it isn't too crowded go to the second level walk and wait for them to come out in the bird feeder area near the entrance.
They have a small gift shop. Ladies at the payment/information desk are very talkative and helpful.
