I find the CRC in FRA excellent. It is large, light, with several areas for rest or work. I have never found it close to crowded. It has a large quiet zone with comfy recliners with head phones. I find the food and booze selection very good, especially considering that we are basically talking about pre-2 PM time frames. There is a good breakfast selection which include fresh rolls, butter, jams and cheese. The wine selection is quite German, but IMHO with whites and sparklings appropriate for a morning drink. There 2 expresso-drink machines with a variety of coffee choices

Don't know about UA's RCC in FRA, but I for one really like the CRC there
