From last month, The Pink Cow in Shibuya has been entertaining the late-night crowd by staying open till 5 a.m. on both Friday and Saturday nights. As extra incentive to rope more mad cows into the corral, they're offering special Happy Hour prices with Sapporo Kuro draft beer, all basic mixed drinks and the house wine going for only 500 yen from midnight till dawn (and all other drinks discounted 100 yen off the menu price). "If no one's here by 3 a.m.," says owner Traci Consoli, "then we'll close early, so the best thing to do if it's getting late is to call -- if we know you're coming we'll stay open." They are also hiring DJs and encouraging all cowpokes to "shake their booties and have a hoof stompin' good time." The Pink Cow: 1-3-18 Shibuya, Shibuya-ku; tel. (03) 3406-5597; www.thepinkcow.com

Bit of the bubbly

Club Shampoo is a new party co-hosted by Phil Miller (of Pylon fame) and Kevin Clone (of TBS Kokogahendayo Nihonjin fame). But as with any party that Phil hosts, the only bubbles you'll find in evidence will come gushing out of a bottle of champagne -- not a bottle of shampoo. The venue for these rooftop barbecue bashes is Yaffa Organic Cafe, right across the street from Starbucks/Tsutaya in the Roppongi Hills complex. They are held every Saturday night 9 p.m.-5 a.m. and feature different DJs each week (alumni include DJ Juri [Gold Finger] and Robert Palmer [Spice]). Entry is 2,000 yen with one drink. (If you're on the mailing list, it's only 1,500 yen, with one drink.)Club Shampoo at Yaffa Organic Cafe: Roppongi La Place, 3F, 5-10-25 Roppongi, Minato-ku; tel. (03) 5770-4788.
