We haven't heard from tallgentleman as to why or what any details are, but I'll play the devils advocate here

. Since we are assuming that his intentions are to meet a provider there (my logic says if that was the case, THE PROVIDER would pick the place), I'll assume his inquiry has nothing to do with meeting a provider, maybe he just wants to get out and sit, have coffee, relax and have a pastry. Maybe he's new to the city and doesn't know where "the locals go", maybe he just wants to go where he might meet someone. There are literally dozens of reasons that he's asking for the advise, maybe, just maybe he posed the same question on some other totally unrelated forums.
