The locals call this restaurant Sourdough Sams, but it's technically Sam's Sourdough Cafe, and is fantastic.
When I first moved up to Fairbanks for college, my dad went with me for a few days. We asked around for a good place to get breakfast, and were referred to this place. I quickly became an addict, and when my father came to visit me again about two years later, the first place he wanted to go was to Sam's.
Service
This place is amazingly popular, so don't be intimidated by the line of waiting customers when you walk in, especially around breakfast time during the weekend. The waitresses are all very fast, and I've never waited more than ten minutes to be seated. Of course, this also means that there is some pressure to not linger over your coffee afterwords because you know that people are waiting for your table. All your wonderful food will be delivered quickly.
Food
The food is incredible. They have a wonderful selection of omelettes, and their biscuits and gravy are to die for! No matter what I'm eating, I always get a side order of these too. Sam's breakfasts are by far the best thing they do, but any time of the day you come in you can get breakfast, lunch, or dinner.
Price
Very reasonable. Just a little bit more expensive than a Denny's and you will have one of the best breakfasts you've ever had.
Atmosphere
Always crowded, sometimes a bit loud. Since this is a small town, there also tends to be occasional yelling across the room when people realize their friends and neighbors have also come to breakfast. Very friendly.
This restaurant recently became 100% non-smoking, which makes it even better.
