Authentic Oktoberfest in CT?

yes, but it already happened:

Only every other year, unfortunately - but a lot of fun!

 

I don't really think the atmosphere is very authentic, but the beer and food is at least. A lot of folks locally love going to this:

+1 for Old Heidelberg. Very authentic food, and there is a beer garden in the back. I worked with a German immigrant who swore it was the best German food in the US. As soon as I saw the title of the thread, that's what I thought of. Drop as much cash in Bethel as possible, and thanks for your patronage!

 

could always go to Noacks and have your own

 

Late August? Stupidly early.

 

Eastside? That's a pretty popular place, never been myself.

Here is a local article, can't vouch for any with the exception of Old Heidelberg.
