I recently ate at the pickle barrel and the overall experience was pretty good. The service was very fast although my particular waitress wasn't overly warm. The garden salad was excellent, filled with mixed greens, lots of veggies and an excellent sweet balsamic dressing. I also had a deli burger which includes hot pastrami, and swiss cheese. It was quite good for a chain restaurant burger, my only complaint being it was a little sloppy on the assembly.
This is a chain restaurant, so don't expect the best meal of your life. However, if your at Yorkdale, looking for decent food at a good price and fast service, it's worth checking out.
