Well, I always say if you're on the DP, then get the most out of it and use your credits for DINNER. The thing is, at Biergarten there isn't ALOT of difference in the buffet between lunch and dinner. I think at dinner you get a rouladen(beef?) that isn't served at lunch and possibly salmon or something else?? Otherwise, the buffet is almost the same b/w the two. We did the dinner on the DP last year, but b/c i didn't notice much difference, we'll go back to paying for lunch here.
