This is the first Swiss Chalet I've seen that has a drive-thru. They should really give up on it, as it doesn't work. It's usually fairly slow (which I get to a point, it's not McDonalds so I know that it'll take longer, but it reaches a point where the concept simply doesn't fly) but our experience this past weekend was epic.
In 25 minutes of waiting at the window, the gent ringing us through gave us change, took the change away, and then gave it back again. I could see him running around the kitchen handling food after handling money at the till. When we finally got our food and made it home, we realized that both of our supplied meals were wrong.
We tried calling the restaurant/delivery number, but gave up after ten minutes on hold. We packed everything up, brought it back to the restaurant, and requested a refund which we received. After everything, over an hour had passed since we placed our original order.
We ended up in Safeway instead, bought a $9 roast chicken and some salads for sides, an were at home eating within 15 minutes of leaving Swiss Chalet.
I really do enjoy Swiss Chalet normally, but it's frustrating when you pay for something and the quality of service (can't comment on the quality of food on this visit unfortunately) is completely lacking.
