It depends what your after.
My favourite pub and it is close to the North terminal( still a taxi ride) is the Black Horse in hookwood - you can book a table online
Amazing food, very popular.

Is a Caribbean restaurant, it has a good atmosphere and some great cocktails, as a regular to the Caribbean the meals are not the same but it's a good evening out
This is also on the high street at the opposite end to Lemongrass next to morrisons.
Another pub type restaurant which is a bit further out from Crawley in the residential areas but worth a visit is the Hilside Inn, great food - not a wide variety to choose from but what they do is amazing, I have never had a bad meal here.

Hope this helps.
