Some friends have recently moved to Welwyn in Herts and want us to go and celebrate a birthday there with them this w/e. Problem is the only nice restaurant within striking distance that they know - Brocket Hall- is fully booked. They're not far from St Albans but don't know anywhere to eat there - just wondered if the collective restaurant reviewers of mumsnet had any thoughts/experience of nice places for a Sat night meal in St Albans or nearby area - many thanks.
