The bigger parking lot is the one sort of across the street from the small one directly behind the building.
On the Google map it's on the corner of Burr and Consaul - as you turn onto Consaul from Front Street it's on the right and has a sign " Parking for Tony Packo's Customers Only "
I'm not sure about the next lot up - I've never had to park in that one - it may be a St. Stephens Church lot
