I would rather avoid Tik-Tak as meet-up location, as well as similar bars/cafés. Loud music/loud crowd, little light, much smoke... These reasons are behind my suggestion to go to somewhere more restaurant-like.
I myself will refrain from proposing further places, as too many options won't make it any easier.
there is actually a non-smoker area in the "bar" in wich it is rather quit, because there aren't any people in there.
