I parked at the Western Ave lot one night a few weeks ago. The machine wouldn't take my card, took a $5 bill but wouldn't take my ones, and then timed out. Had dinner and returned to the car to find an envelope stating I now owed them $35. The next day sent a letter of explanation and a check for $3 (the lot is $8 at night). about two weeks later got a letter stating I now owed $60 because I hadn't payed the fine in 15 days.
Pros: close to Typhoon restaurant
Cons: use at your own risk
