Anyone recommending Hitchin- do recommend some restaurants there please

I didn't see many when I visited other than pizza express!
The Hermitage, Los Reyes or Bar Azita for Mediterranean/Tapas, Lussmans. Loads of coffee shops and cafes, Chia next to the church is really popular for vegan food.
There are some excellent pubs for food: The Victoria, The Highlander, The Albert, The Radcliffe Arms, Kite at the Red Hart. And loads of really nice pubs serving food in surrounding villages like Ickleford, Pirton and Gosmore.
Also loads of great Indian restaurants, Japanese, Thai, Chinese. And a monthly streetfood event. The type of house you're going for is likely to be near the town centre and the station so you would have excellent access.
Hitchin is now on the Thameslink line so has direct trains to Brighton and London stations like Farringdon, Elephant and Castle and Blackfriars as well as Kings Cross/St Pancras and Finsbury Park. And in the other direction to Cambridge or Peterborough.
The town has changed a lot in the last decade. Young families moving out from London have given it a much trendier image, like a slightly cheaper St Albans.
