...I don't know you.
I've been to Fentons for over 10 years. And it never ceases to amaze me how great their ice cream is. What's special about Fentons? The ice cream is made on site (hence the creamery title) and you can purchase their ice cream to go. The portions are huge, prices are very reasonable, and the service is fast. There's usually a line out the door and around the building on the weekends and at night (open to 11pm on everyday and Midnight on Fri and Sat). Fentons is a local landmark and many generations have been going there for years. Fentons is also a great place for the family. I've only ordered the ice cream, so I have no idea what the other food items (burgers, salads, etc.) are like. But if their ice cream is any indication of the quality of their other foods items, I'd have to say the food should also be great. Oh, and they take reservations!
PROS: Best ice creamery in the Bay Area. Casual and nostalgic atmosphere. Very Reasonable prices for the amount of ice cream you get. Popular among the locals. Great for birthdays. Just go there already.
