The lqs near me does have a number of your suggestions, 2 nights a week they stay open till 8 pm, and some of their classes are offered on those nights, which means those of us working girls could possibly take a class after work. Some are also offered on Sat. but if your working there is a lot of competition for Sat. time, and they generally keep the Sat. classes to one day, sometimes all day.
They do have a website and a newsletter. Most if not all months there is some promotion in the newsletter. This month it was if you spent $20.13 you would get 2 free fat eights of your choice from the f8 bins.
They also do one day a month on Sun. when the store is closed you come in and work on whatever your own project you want. There is a fee but they provide pizza and if you do need anything supply wise if they have it in the shop you can buy it while you are there.
