 Person1:       I need a suggestion for a restaurant here in Manhattan .  
 Person2:Certainly ! How much are you planning to spend on dinner , sir ?  
 Person1:        My date's very sophisticated , so I'm sure she would expect nothing but the best .  
 Person2:May I suggest our own hotel restaurant ? It got three stars in the latest restaurant review .  
 Person1:        No , thank you , I want to go out on the town . What other ideas do you have ?  
 Person2:There's always Gramercy Tavern . They have live jazz . The food is delicious , but very expensive .  
 Person1:        That sounds like a good place to take a date . Can you make a reservation for me ?  
 Person2:As you wish , sir . You'll have a wonderful time there . 
answer:
formal


question:
 Person1:       Do you want to go out for dinner tonight ?  
 Person2:Sure . Have you got anywhere in mind ?  
 Person1:        I'm starving , so maybe we could go somewhere with large portions .  
 Person2:That Italian restaurant in the city centre always has large portions . Do you want to go there ?  
 Person1:        I'm not really in the mood for Italian , actually . I was thinking of something a bit spicy .  
 Person2:If you want spicy food , then I'd recommend going to a Thai , Indian or Chinese restaurant . How about that Chinese buffet on Cowley Road ?  
 Person1:        I really like that restaurant ; you get a lot for your money there . But , they've westernized their food , so it's not actually that spicy .  
 Person2:You're right . Most of their dishes have sweet sauces . We could try that Indian restaurant just down the road from us .  
 Person1:        The Taj ? They're a bit expensive , but they do serve large portions of very hot food .  
 Person2:The Taj it is then .  
 Person1:        Shall we bring our own bottle of wine to save some money ?  
 Person2:They'll still charge us a corkage fee .  
 Person1:        That's right . It'll probably work out to be about the same then anyway .  
 Person2:Don't worry about money . I'll treat you tonight .  
 Person1:        Are you sure ? We could go Dutch .  
 Person2:No , I'll pay . It's my turn anyway . You paid last time .  
 Person1:        I won't argue with that ! Let's go !

informal

 Person2:I'm sorry . I forget all about it .  
 Person1:        How could you ? I reminded you just this morning .  
 Person2:It's leap my mind . I really feel terrible about it .  
 Person1:        I have been looking forward to this performance all month .  
 Person2:I'm really sorry I let you down . I'll make it up to you somehow .
