If you have 2-3 you'll feel super bloated as Duvel is known to "make the yeast rise" in your belly
I was just in Bruges, Belgium the other day and had a great one but the name escapes me right now; they make like 400 beers though, so I'd guess a large majority of them are better than Duvel
For fruity beers, Kriek is great if you like cherry flavor.
