U: I'm looking for a restaurant that serves gastropub.

S: There are four gastropubs in Cambridge. Is there a price range you prefer?

U: Expensive. And in the centre, if you can.

S: I have the Backstreet Bistro or The Slug and Lettuce. Would you like me to book a reservation at one for you?

U: Which of these are known for having good atmospheres?
S: Customer reviews called the atmosphere at Backstreet Bistro bad and a bit of a letdown. Although one reviewer found The Slug and Lettuce to be loud, the others described it as fun, lively, happy, and friendly. Would you like to book The Slug and Lettuce?
