City jets in 1.95 are fine. Plenty wide, available in amberwall or blackwall. You can get them in 1.50 as well, but seeing as you mention "around 2.0", I'll ignore those.
Bontrager Hank is a 2.2" dual-compound full slick. The amount of grip is just insane, but they are so high that the diameter goes up to nearly 27". Not a problem on a bike with a low BB, but with a higher bike you may experience slight difficulties getting on the bike. Good puncture protection and I don't see any sign of wear after 1K+ miles.
There's also the Schwalbe Big Apple in 2.0 and 2.35" variations.
I've used both sizes for a while and wouldn't recommend them. Too much carcass flex made the bike "seek" its own line whenever you were braking, accelerating or cornering hard. You can literally feel the entire front or rear end move sideways by about half an inch, even at 60psi.
Not enough rubber to provide any puncture protection either.
