Have eaten here many times for lunch and dinner and have always found it to be pretty good.
The 'two can dine for £14.99' is really great value and there's a pretty decent range of options to choose from.
The portions are all big so you definitely get value for money.
The coachman itself is nice and has a good atmosphere about it. Although I think at the weekends it gets pretty busy so best to book a table probably. During the day though it's fairly quite so nice just for a quiet lunch and drink.
