You have lots of good cheap choices in that part of town! What type of food sounds good to you? There are Italian restaurants, Indian, Spanish, Chinese, and more.
How about Chinese? can you book me a table for 3 people at 18:15 on a Sunday?
I'm sorry, none of the Chinese restaurants are available at that time. Is there another day or time that would work for you?
Ok, I'll try for a little earlier, how about 17:15?
