My fiancé and I ordered their chicken sandwich to share, and their portion is huge. So either go with the mini or order their normal size sandwiches if you have a big appetite or for sharing. We added provolone cheese, mushrooms and jalapeño peppers, and surprisingly the jalapeño peppers had some good heat!
I've been to California sandwiches in the Queensway location, and had their schnitzel and nothing to brag about. But this chicken sandwich was the bomb. It was packed with some sweetness and tang from the tomato sauce, and nice heat from the jalapeño and balanced flavours.
The only downside is the bottom half of the bun gets soggy if you order it to go. Otherwise it's amazing and I'll be back for sure!
