Where to eat - Renaissance Heathrow

We have booked a nights accommodation prior to our April Virgin flight as we got a good deal with parking. Hopefully (dare I say this) we are looking to arrive at approx 7-8pm and so will need somewhere to grab a bite to eat.
Now I'm not always that fond of hotel restaurants - esp airport based - as I find them to be wildly overpriced so I was hoping that someone can give me a bit of advice where to eat. Ideally we won't want to drive although a short taxi / bus ride isn't out of the question.
So, should we stay at the hotel or wander further afield?
Breakfast the next morning isn't a problem as we will be able to use the Clubhouse
