This place was a life saver more than once during my stay in Pittsburg. They are open 24/7 which is amazingly convinient. They staff was vey helpful and willing to engage in conversation about places to eat or where to buy booze.
Their prices were fair and they had a large selection. Late one night we stopped in to buy a snack and I really needed to use the bathroom. They didn't have one but she told the employee of the upstairs business to let me use the bathroom. That was great.
I imagine I will be back before my trip is over.
