Hurray! I have found the croissant fix I was looking for. This was facillitated by having to take my car in for service by 8:00 am, on University Avenue. I finally got to the Trung Nam French Bakery before they were out of croissants for the day. (This is not a patisserie like Patrick's sounds like it is.) The croissants were excellent; my coworker who lived in Paris agreed!
They're at 731 West University Ave., west of Dale on the North side of the street.
On to Patrick's when I am next on that side of town.
