Not at all, like nlativy says coffeshops are everywhere in Tokyo. Yes, most are smoky, but completely separated smoking areas and even completely non-smoking places are becoming more common. Also, some mom-and-pop coffeeshops have very good coffee, including a good variety of beans. For me, the main problem isn't quality, it's price. I don't want to pay 400~500 for a cup of coffee.

In any case, if you care at all about coffee why would you even consider Nescafe as an alternative, instead of good old brewed coffee?
