I can say from experience that this isn't necessarily true: my Aunt's dog regularly ate chocolate before it died. (The dog died of old age, I promise.)
It once consumed two entire boxes of Russel Stover's chocolates and was fine. (The veterinarian was panicking, of course.)
It is true that dogs can't effectively break down the theobromine in chocolate, though. In theory, they should die from eating a somewhat significant amount.

Now, as for my favorite chocolate...
Since I don't consider any chocolate with filling (Cadbury eggs, for example) truly chocolate, I'd have to go with either Dove chocolate for "milk chocolate," and Hershey for "dark chocolate."

I only like Peanut butter cups and Resee's Pieces. All other chocolate is evil and should be destroyed ;)

While I was doing a Chekov show (Three Sisters), the director brought in some Russian chocolates. I am not to particulary fond of chocolate to begin with, but I really disliked the Russian chocolates specifically. If I had to choose a favorite chocolate, I really did enjoy Belgium chocolates when I was visiting Belgium, as well as Fanny May chocolates from (my hometown) Chicago.

Cadbury's my all time favorite. Yeah, I also prefer European chocolate but I don't mind the Maltesers or Reese's now and then. I miss the Kinder egg chocolate. I don't know why but I do. (I can't even remember how it tastes--i was just in it for the little toy inside) ;) I also have this thing for those After Eight dinner mints.
Hershey's chocolates smell weird. Especially the Kisses. I don't know...

Dove dark chocolate, or Godiva truffles. I hardly ever eat white or milk chocolate anymore.

Fav. Chocolates:
1. Neuhaus (omg, so effing good) www.neuhauschocolate.com
2. Godiva (yum)
3. Ferrero Rocher. ^^

Dislikes:
...any cheap ones. lol

Canadian chocolate is where it's at (yum yum, Bernard Callebaut...chocolate).

I also like Hershey or Cadbury chocolate (or their chocolate bars, at least). But I really wanted to try Ferrero Rocher, but...allergies.

Chocolates!
 

Mmm...chocolate. I hope that we're all humans here, so I guess that almost all of us like chocolate, right?

Since I've started shopping at a little co-op store that doesn't sell cheap candy bars but sells all sorts of fancy organic chocolates, I've discovered that I love really dark chocolate. The 71% cacao Valrhona bittersweet dark chocolate is really incredible (it's weird, but my whole body feels good as it melts in my mouth), and the cheaper very dark chocolates are nice, too. Dagoba's 87% Eclipse organic chocolate is really interesting, and I like it quite a bit, though I can't really eat it in huge quantities...not that I eat any chocolate in huge quantities...I don't want to LOOK like a chocoholic, too! It's a lot more bitter than sweet, but it's still quite an interesting and nice taste. I really, really want to try the 99% cacao chocolates that Lindt makes sometime, though I've never seen them in stores anywhere.

I like nice sweet milk chocolates a lot, too, and even white chocolate and cheaper chocolates like Hershey's is nice now and then.

So, what kinds of chocolate do you all like?

I'm just going to merge this with the existing chocolate thread.

If you guys want some very tasty, cheap chocolates that are eons better than Hershey, just try Milka. It isn't that hard to find, and most specialty candy shops should stock them. Mmmm.

And dark chocolate is my favorite variety of chocolate. I'm not too big a fan of white chocolate, though.

I'm allergic to chocolate.

Once my sister gave me a small piece of Godiva chocolate before I started itching like crazy. But it was quite good.

QFT. Swiss chocolate is absolutely heavenly too! I even went there to have some ;)

I love just plain milk chocolate by itself. I don't like dark or white chocolate.

Same here. I loooove chocolate. Chocolate from pretty much any foreign country is amazing. Trader Joe's has some milk chocolate with almonds that is delicious.

White chocolate, despite not actually being chocolate, rocks in small quantities.

I'm not hugely partial to milk, but dark chocolate is something I could eat all day.

Capi here stole the words out of my mouth. I'm not really a sweet tooth, so white chocolate is waaay too sweet for me. Kinda revolting when I think about it. As for dark choc. the more bitter the better. There was once I ate this brand; can't remember the name; the dark chocolate was so bitter, it's like chewing coffee beans. Not that I don't like it though. Anymore bitter and it'll taste like medicine.

I particularly like chocalate with liquid filling; cherry wine for example. Add a little alchohol flavor into those sweet little things and hmmm....

Im not as big on chocalate as I used to be, but I do love Risen. I love to have one around my desk to suck on every now and then. Helps me concentrate, and they are very tasty.

Oh...sorry about that!

Truffles are pretty yummy. I usually like plain unflavored chocolate more than anything else, though. Plus, I always give into the temptation to chew on truffles to get at the filling.

Actually, AkirA, dark chocolate gives a nice burst of energy and helps me concentrate too. A square of Valrhona Le Noir Amer will make me bubbly and happy and energetic for hours. I don't think that it's just the sugar, because drinking a vending machine bottle of Coke (which has more sugar than an entire bar of that chocolate) just makes me feel jittery and burned-out.

My parents and sisters all HATE dark and milk chocolate...they'll only eat white chocolate, and maybe flavored light milk chocolate. Weirdoes. On the other hand, if someone sends my mom chocolate candies for Easter or Mother's Day, she always gives them to me. The only thing better than great chocolate is FREE great chocolate!
