We used to go to the now, sadly closed, Oak Ridge Lodge, or something like that, in Milton, NJ. Absolutely fabulous German place. Live music, entertainment, and generous portions (unlike most German restaurants).
We have tried others. Mostly dissappointing. Like, Triangle Hofbrau is OK. Some place off 287 was just OK. Have heard you leave Black Forest (Newton area) hungry, though the food is supposed to be good.
Any suggestions for Oktoberfest out there??
