I have three characters going out for lunch on a Saturday. Two are in their mid-twenties, the third is a bit below 20. One of them is a local, and it's her birthday. The other two are friends visiting her on the occasion.
The birthday girl is the trendy, updated sort who likes to go out much, something of an adventerous eater and has a dislike for anything too high-class or posh.
One of her friends is from a very wealthy family but has distanced herself from them, and has the food preferences of a four-years-old. She knows the city back and front but hadn't been there much in a few years. Her boyfriend is from a mid-sized California town, of Asian decent, visiting New York for the first time in his life. He's the youngest of the lot.
I want them to go somewhere fashionable and cool - what with an upbeat birthday girl and a wide-eyed tourist - but not too flashy or ridiculously high-end. (Though it may be assumed that money is of no issue.)
