Let's get this out of the way upfront: the chicken dinner isn't really worth $25 or whatever ridiculous price they're charging for it. It's like an Apple product. You're paying extra for the name.

That being said, the food is legitimately quite tasty. The original chicken dinner, the famous one, comes with a ton of good-tasting sides in generous portions. (I definitely recommend getting it family style.) And the chicken itself has this amazing seasoning that's to die for. (conveniently, you can buy it downstairs!)

If it's a special occasion, or you've never done it before--sure, go ahead and spend the $25.

If someone else is paying, by all means spend their money!

Otherwise, save yourself some money and only go if you have a discount (e.g. the birthday club lets you get a free meal in your birthday month). Or just eat downstairs in Z's Cafe. It's the same food, you just get less of it. Or even eat across the street at Bavarian Inn, which is half the price but tastes almost identical.

For other things, the service has always been excellent at Zehnder's, and the place is always nicely decorated for the season. They also have a fantastic bakery downstairs and make amazing cakes. They're also good for events like wedding receptions--not cheap, but they'll work with you on the menu and do very well.
