Did a flight controller ever answer Flight with a no-go? 0
OK, all flight controllers, I'm going around the horn
Retro? Go
FIDO? Go
Guidance? Go
Control? Go
TELCOM? Go
GNC? Go

Are there any recorded instances of a No-Go?

One thing to note is that these polls of the room are largely for-the-record - in other words, if a flight controller was sitting on a problem that would prevent the accomplishment of a major milestone, and didn't tell Flight about it until the poll, that flight controller would not be in MCC for their next shift.
That said, and apologies because it's anecdotal, I've heard it at least once on the loops myself.
During the first attempt to launch STS-088, when Ascent/Entry Flight Director John Shannon polled for a go for launch, Weather (the controller position) was "no-go, forecast no-go" (meaning that current conditions were outside of flight rules, and were not forecast to improve by the launch time)1. Despite this, Flight reported to the Launch Director at KSC that Houston was go for launch. The Weather guy couldn't believe what he was hearing and requested clarification from Flight on the loops, and was shot down.
That was a weird launch attempt for several reasons and I'm kinda glad it got scrubbed. The next day everyone was on their A game and it went off fine.
1This wasn't news to Flight, it had been reported to him previously.
I don't think Weather being no-go for launch is particularly novel; this just happens to be one that I was there for.
