If you’re in the area of Union Station you might want to drop by the Thai Festival that’s been running there through the weekend, celebrating 75 years of U.S.-Thai relations. They’ve got music, crafts, history, orchids, a kick boxing ring, and of course tons of Thai food. Admission is free, with booths and displays sprinkled around the station, and food all over the place. (Food is not free, but it’s good and spicy.) Hurry if you’re interested; this is the last day so you only have this afternoon to get there.
