Great haircut, great price! Good conversation too! Hours change a bit when students are out of town, so for spring break, summer and winter break. But you can always call her voicemail to see if she is open or if hours have changed at all.
I've been here three times now and usually the line is not too long as long as you don't go at peak times, such as late afternoon when the students finish class. But if you go between 11 and 1 you probably shouldn't have to wait too long.
