China Gate, 1201 South University Avenue, Ann Arbor

A couple of problems here, though I hate to cross this place off my list because they have the most inexpensive and delicious Peking Duck anywhere.  One problem is the door-vestibule-door arrangement at the entrance, which is not unusual, but this one requires a sharp left in the vestibule, which isn't exactly large enough to do the 3-point turn you learned in drivers' ed.  Once you get through the doors, the tables are accessible but the bathroom is down the basement.  Unless you're a complete Thimblebladder, you can probably get by using the facilities in the nearby University buildings or the Starbucks across the street before entering.  Bottom line: some difficulties, but doable.
