The first time we took our youngest, she was only 3 months old. We had no problem taking her into the Biergarten in her stroller(a full size stroller). They sat us at a table where there were already people sitting on the aisle, so I had to put the stroller by the railing...there was NO room for it, but we made it fit and everyone was very accomodating. I doubt you'll have much trouble if its a necessity.
