The Chicago Botanic Garden is located right off the Edens at Lake Cook Road (so technically, it's not in the city). We are members, so the parking is free (otherwise, you will need to pay). It is truly wonderful to visit there when everything is in bloom, and hard to believe that the expressway is about a mile or so away. Bring your hiking/walking shoes, as there is a lot of ground to cover. I don't know which area we like the best - the English garden, the rose garden, the Japanese island/garden, the fountain area (or maybe it's the cafe which looks pretty good after all of that walking.....). They also have a nice gift shop as well. The CBC also has a plant and bulb sale, as well as other planned special event activities throughout the year. Also, when we were there a few weeks ago, a bridal party and photographer had arrived to take bridal party pictures; I don't know what the CBC policy is on that (ie they may have restrictions on day/time/areas to photograph), but it's worth checking out if you know someone who is getting married.
