Average average average.
Do not get anything vegetarian because you'll feel like you could have just made the food yourself by popping down to Sainbury's, hitting the frozen food section, buying some vegetarian sausages and burgers, going home and cooking them in loads of oil... The result would be the same.
The Vegetarian burger is horrendous. Unimaginative, pre made and awful and oily. The vegetarian breakfast - again, unhealthy and not what health-conscious vegetarians want. I feel like the food is lacking care and imagination and the service is pretty bad.
It's not overly expensive, but for what you get it, it's bad value.
