not like it used to be. when i was younger my family and i went to joe kool's very often, as the food was always great and the service was good too.
i just went for my first time in probably 6 or 7 years and it is nothing like it used to be. the regular fries aren't fresh cut, the sweet potato ones may have been, i'm not sure. my mother ordered the sp fries and they were cold. i ordered a club sandwich. it was okay, but it seemed to be made with mediocre ingredients. the sandwich my mother ordered (some sort of chicken thing) was very boring and plain, and it came with lettuce on it, even though she'd asked for no lettuce.
our server did comp our drinks because of the sandwich mishap which was nice, but other than that i found the service to be lacking.
i'd recommend walking up a few blocks and hitting up the church key if you want good food. pricier, but definitely worth it.
