Barclay Prime This hip-ified steak house with mod green and yellow furniture is the latest opening from restaurateur Stephen Starr. While some price-gouging is going on (you pay extra for sauce, and the Prime Sidecar costs, no joke, $30), the prices are mostly sane. The 20-ounce rib eye and the porterhouse are first-rate, as are sides like the shaved potatoes with onions. DETAILS 237 S. 18th St.; 215-732-7560.
