We hate beer, and we didn't like the soup. There was a definite bittery beer taste when we got it. We normally love any other cheese soup from all the other (non -WDW) restaurants we've tried too. My brother usually LOVES any type of soup, and he was picking away at his, not exceedingly thrilled.
It's not terribly expensive though, so I'd probably order just a cup and see what happens. If you end up liking it, I'm sure your server could probably get you a second cup pretty quickly.
None of our group thought the cheese soup was that good. We all said that the Walkabout Soup at the Outback was FAR better. In fact the entire meal at Le Cellier SUCKED. Great service; good atmosphere; HORRIBLE food. OK, the desserts were good .... but that's it.
DH and I don't like beer either, but we got the soup. Now, I'm not sure if we would get it again as it wasn't as good as most people swear it is. But it was tasty with the bread, or as a soup depending on your taste. Not amazing to us, but worth the try just to have tried it.
