I've got a very happy belly right now...
Geno's is a small local chain that seems more like a big National chain. I've been growing rather fond of this franchise lately. There are about half a dozen or so locations around the Valley, and each is owned by different people. This location happens to be one of my favorites (this owner's other location is my other favorite), though I do like them all.
Having sampled the cheesesteak a few times, I can say with confidence that it's superb and authentic. I've also now tried their pizza, and that's also excellent. There's a lot of flavor packed into every bite of food I've had here, and you get a lot of bang for your buck.
This is the sort of place you'll get a craving for. I'm slightly outside of the delivery range of this spot, but it's easily worth the drive. The prices here are great, it's clean, the staff is friendly, and the food is delicious and awesome. Can't really go wrong. Not sure what else you would need to make a place 5 stars.
