UPDATE! Sheesh, I've been giving wrong directions. Big Fatty's is on Maple Street in Hartford, which is also known as Route 14. Best to use the link Big Fatty supplied (below), as I am obviously ALL WET when it comes to directions! (But the Huz could've told you that!)Big FattyHimself has left a link to a Mapquest map. Here's how to get there ... now do it!
And the lovely Ilsa commented that if you know how to find the Elk's Club, you've found Big Fatty's, because they're right next door.
There. I hope I've made up for all the misdirection! Sorry, folks!
