Stopped in here for a quick Guinness. Definitely a bar/sports bar format you'll recognize if you are from UK or America. Nothing fancy, but they have a good selection of beers and bar food. Open almost the whole day so you can get breakfast here as well. Short walk from center of Kiev (Maidan Nezalezhnosti) - just down the street from St. Michael's and the Hyatt Regency. Everything is online (http://www.obriens.kiev.ua), so you can check out easily. As elsewhere in Kiev, lack of Ukrainian language skills is not an obstacle to getting good service and understanding the menu.
