Lancashire is rich in two things: food and comedians. So if you plan to go out for an entertainment night a book a seat in the theatre for a comedy show, you might want to add the final touch by dining at a good restaurant.
As far as the choices go, New Season is a fine restaurant. It is a Mediterranean style restaurant with a Moroccan ambiance and Tuscan music in the background. Quite naturally, the food is dominated by Mediterranean dishes. The place is known for its large portions, therefore, you might want to keep that in mind when you order for two or more people.
The other place you might want to visit is Amalfi, which is an Italian restaurant. It's a great place, although a little expensive. Therefore, if budget is a concern and you'd still like to try this place, you might want to visit during lunch hours or take advantage of the early bird special.
