We recently ate at the Biergarten in Germany and LOVED it - it was just lots of fun! We were only two, so they put us with other people (8 at the table) and you end up talking and laughing with the others that you meet. Also, the entertainment was a novelty And we didn't have any advanced reservations...we made them that afternoon.
We've eaten at the Rose and Crown on several different trips and always enjoyed it. The food and service are always good and we've never been disappointed.
We just ate at Biergarten and all enjoyed it. Watch for the times for the entertainment and I'd suggest going 15-30 mins before it starts.
It's fun and the food is quite good!
Highly recommed it to you!
