Unfortunately, we don’t have anything to report today about Federal Donuts, Zahav, nor newly opened Citron and Rose. However, we can tell you that Cook+Solo’s Percy Street BBQ is offering an all-night happy hour in honor of its third anniversary tonight, and rolling prices on its Texas-style barbecue dishes back to where they were on opening day in 2009. Colorado’s Oskar Blues is crashing the bash, and in honor of its tenth anniversary, will be offering its beers for $3 a can. There will also be dancing, rock-country-and-blues jams courtesy of John Francis and the Midnight Choir, and a massive beer-drinking cow-shaped cake. The fun starts at 5 p.m. and goes to 11 p.m.
