U: I need a moderately priced restaurant in the south of Cambridge

S: I have two restaurants in the south. They serve italian or modern european.  Would you like information on either of those?

U: No, I was hoping to eat some South African food.

S: Is there anything else I can help you with today?

U: Sorry, not sure I follow.  Can you recommend a south african food restaurant?  Thanks.

S: Unfortunately there are no restaurants that serve South African food but I can look for other types of cuisines if you want.

U: Modern European will be fine.  Can you reserve a table at one please?

S: Yes, I will book you a table now.

U: Thank you. I need it for 4 people at 12:15 on Saturday

U: Actually, do they happen to serve any beer?
S: While I do not know if they serve beer, Restaurant Alimentum does have alcoholic beverages on their menu.
