Every time a new restaurant opens on Grass, we’re amazed at how much secret space it’s actually packing behind its barely half-block facade. The latest to join the ranks is Powder Room (Grass, 264/1 Soi Thong Lo, 02-715-9282), a new venture from the folks behind Spring Summer boasting an alledgedly NYC vibe. Is it just us, or is NYC style becoming the latest restaurant trend? In other news, we noticed that the Red Mango that used to be there is gone—it probably got intimidated by all the sexy competition. We’re curious about what it’s going be replaced with.
