Let me start with, do not plan on being seated in less than an hour to an hour and a half on a Saturday night at this location. My friends and I put our names on the waiting list around 7 and did not get seated until close to 9pm. We actually ended up getting a couple drinks at a bar close to the Cheesecake Factory and another at the Cheesecake Factory while we waited. I am definitely not complaining about this since it is typically this busy on Saturday nights in South Side.
The service, especially for how busy it was, was FANTASTIC! I wish I remembered our waitress' name, but she got us drinks (waters because, you know) and checked back multiple times for when we were ready to order. Typically you'd expect the service to be slow and hard to get when it's this busy, but we ordered and our food was out in probably 30 mins tops! I got the Chicken and Avacado Club Sandwich and it was deeeelicious! Everything was hot and crunchy - it was worth the wait! However, one of my friends ordered a cheesecake from the front counter before we left and that took almost 20 minutes or so to get, which I didn't really understand.
If you aren't in a rush, I'd say just stick out the wait because it is so worth it! They let you take the buzzers out of the restaurant, as long as you're in the restaurant 15-20 minutes before your buzzer should go off. It ended up being a nice dinner and I was definitely impressed with the service and food for how busy it was.
