Kevin's Deli is this amazing little place that can be found in Webster Hall in Oakland. The easiest way to find it is to turn down N. Dithridge Street from Fifth Ave and pull off to the left into the loading zone. (You'll see the deli's window on the first floor to the left of the entrance.) Enter Webster Hall at this entrance and you'll find Kevin's Deli to the left.
I'm not sure how I first learned about Kevin's Deli, but I suspect it was one of the few reviews here on Yelp. Shortly after, a Groupon became available so I jumped on the chance. Not that the Groupon was necessary since Kevin's Deli is super-cheap. Most items on the menu are $5 or less. It's a bargain but well worth it. Kevin knows what he's doing with the simple things. Like the Turkey Bacon Club with fresh turkey and bread that is toasted to perfection. I don't know where he gets his steak or what he does to it when he cooks it but I've had both the steak pita and the steak hoagie with fries and been amazed at how great it tastes. I will be back to try some of the other items I've read are good. Like the chicken salad, pasta salad or even that pound cake. He also offers many breakfast items but I think most people go in for the lunch sandwiches.
I suspect that most of his business comes from local businesses and college students. Don't go late (Kevin's Deli closes at 4:30pm) or on the weekend (open Monday through Friday). You may be confused because he operates out of a very small room that was likely someone's office at one time. But if it's lunch time and you're in Oakland, you can't go wrong for the price. Kevin's Deli may be small like the prices, but the taste is bigger than you'd expect.
