This particular location is my favorite. I've been to the one in Sac but it doesn't have the same ambiance (comfy booths situated inside caves!). The "Big Night Out" dinner is a MUST that you have to splurge on (I think it's $48 per person). This is a very relaxed, well paced, fun, interactive dining experience that lasts for hours - which allows you to drink plenty of wine from their great wine list in the process. For the best time - go when it's foggy or cold out (December through April). It's a great spot for a date and even better for a double date.
Pros: Classic Swiss Fondue, Tempura Praws, Chocolate Fondue
Cons: Long drive from Walnut Creek :-(
