Vee like zee French chairz, but they are usually VERY expensive. Real French bistro chairs made by companies like Poitoux or by Maison Gatti out of rattan and rilsan (a natural polymer) can go for $700 a chair. Rollhaus on Grand Street has a great low cost alternative: they look the same and are super sturdy commercial quality.
Primarily selling to restaurants, they stock a complete line of these chairs in many styles and colors which substitute a soft plastic for the seat material. The white ones in the window are for sale for $99 each, while the regular price is @ $125 per chair. It's a great deal. You can check some out on their site right here.
