U: I need to find a restaurant that serves Weish food in the centre of town please.

S: I'm sorry, but there are no restaurants that match your criteria. Would you like to broaden your search?

U: Yes, are there any Weish restaurants in the cheap price range that are in north Cambridge?

S: I'm sorry, but there are no welsh restaurants in all of cambridge.

U: Can you change my food preference to Chinese then? I still want to be in the cheap range and center of town.

S: I found 3 options for you: Charlie Chan at Regent Street City Centre, Rice House at 88 Mill Road City Centre, and Golden House at 12 Lensfield Road City Centre

U: Does Charlie Chan have big portion sizes?
S: People differ in their opinion on the portion sizes at Charlie Chan. They have been described as both generous and tiny.
