I am looking for a restaurant well known to locals with good american or italian food
Yes - Gramercy Tavern is perfect for american food and Tratorria for Italian
Are they both walking distance?
yes- they are
How is the wine and drink menu?
Both are excellent
and the atmosphere?
both are great, Gramercy Tavern is more "lively"
Understood. Could you help me make reservations?
Absolutely. What time and which restaurant sounds good?
Lets do Gramercy Tavern for two.
They have a fixed menu and a la carte seated in different areas. Which sounds better?
A la carte 
Great so I will make you a reservation in the tavern section. What time?
8:30
Unfortunately, they don't have an 8:30 open. I can get you in at 7:00 or 9:30 for two in the tavern. Or I can get you in for the prefix menu at 8:30
What about for tomorrow?
The restaurant said 8:30 is also booked for tomorrow.
Actually, I am getting hungry let's do the 7:00 PM
Perfect I have you confirmed for 7:00 PM. Anything else?
No that's it.
Have a wonderful meal
