I know that all Melting Pot locations gets mixed reviews... usually the price turns people off.  It is a little pricey, but it's all about the experience.  Also, since it's a time-consuming experience, one tends to be there about twice as long as at a regular restaurant.  So I don't really mind the price for a once in a while kind of thing.  My hubbie and I have been 8-10 times... twice at the Scottsdale location.

The husband and I always order the "Big Night Out," generally the "Lobster Indulgence."  (We figure if we're going to spend a pretty penny, we might as well really make it worthwhile.)  Maybe since we always do the lobster thing, the price doesn't bother me as much.

Don't remember the specific themes the times we went to Scottsdale, but the "Big Night Out" meals go like this:  Cheese Fondue (you can choose the special or any from the regular menu) with assorted dippers, Salad Course (again, the special or off the menu), Main Course (if you get the "Lobster Indulgence," it includes twin lobster tails, usually a couple kinds of beef (e.g., filet and sirloin), shrimp, chicken, salmon, and/or pork, often a stuffed pasta, and lost of vegetables) with assorted sauces, and the best part... Chocolate Fondue with fresh fruit, brownies, marshmallows, Rice Krispies Treats, etc.  Yummy!

I must say that your experience also really depends on your server.  If you get a bogus one, you might not have a great time.  We've had good experiences for the most part, some absolutely awesome experiences.

Also, check out each location's web site prior to making reservations.  They sometimes offer really great deals or promos, especially on weekdays.  This info might be helpful to those who feel like the regular price is over the top.
