The Pop 5 best outdoor restaurants list is out, but allow me to add a footnote: Lexington Social House (1718 Vine St., 323-461-1700). It had its official grand opening last night with celebs like The Hangover Part II's Jamie Chung, Jaime King, Amy Smart, and Mario Lopez. The indoor dining room is gorgeously romantic, but its outdoor patio is perfect for dining al fresco in the Summer. The left side has tables for sit-down meals, and the right side is lined with comfy, stylish sofas for lounging, sipping, and munching. Click through for snaps from the star-studded bash, and get a closer look at the fabulous outdoor space. Then make a reservation, and asked to be seated outside.
