The video below will give an overview of Singapore Airlines' SilverKris Lounge in San Francisco. Unfortunately, the lounge is not split into first and business class sections. What does that mean? Well now, instead of their being a separate space for first class passengers, all 50 premium-cabin passengers - eight in first class and 42 in business class - are sharing the same (rather-small) space. Granted, most of these passengers aren't showing up early enough to spend time in the lounge. That said, it is a minor downside. The only real noticeable difference is the quality and quantity of foods. The lounge itself is marketed as a "business class lounge" and as a result serves food on par with what other business class lounges serve. They do offer two or three hot dishers, but they did not look very appetizing. The real saving grace to this lounge were the huge floor-to-ceiling windowns that ran the length of the space, looking out on to the tarmac. At the end of the day, the seats were fine, the internet worked well, they had a printer if needed and the scotch was refreshing. Was it the on par with the SilverKris business class lounge in Singapore? Of course not! But it's a perfectly adequate place to spend an hour or so before departure.
