I really liked 61B cafe until ... recently ... they change the cups and they leak ... a lot. Not a big deal if you stay at the store: you can ask for another one. Also, the lids are very thin and not the same at it used to be. So, the coffee spills easily around ... This is so inconvenient when you take your coffee in your car ... good luck for keeping it clean!
Also, the size of the pastries decreased seriously while the price stay the same. They are good but now, clearly overpriced. The coffee is also clearly overpriced, I paid more than $2 for something that looks like a small coffee in any other coffee shop in Pittsburgh.
Last thing: this is a cash only place ... Common guys, let's be serious, everybody takes the credit card now ... and you have so many solutions to take the card ... at the prices you charge the coffee, there is a lot of margin to pay the credit card processing fees ...
