There's a newish place on 5th Ave in Brooklyn called Perch. I've been a few times. It's a nice looking place, a sort of modern diner, based on the menu. A couple of weekday visits made me like the place, but a weekend visit was an absolute horror.
It's one of those places where you order at the counter, and they give you a number. But there's no way for them to see your number unless they go around to every table and look at it. Peoples' drink orders get confused with regularity, orders come out at different times, etc.
The owners and staff are very friendly -- hopefully they'll work out the kinks. I've tried various menu items including huevos rancheros, mott st sandwich, and cobb salad. All are solid, not amazing.
Overall, I'd say it's a great place to hang and read on an off hour.
Anyone else been?
