Ok so I literally just left and I figured this was gonna happen. I asked for a specific piece of pizza because I saw there were slices stacked from the last pizza and I wanted a fresher one. Of course the older slice is grabbed and I politely asked for a different slice. I explained it was my cheat day and I’m literally eating here because I’ve been waiting all week. Of course the switch happens during the warming. I know it’s the piece because I wanted a middle so less bread. And the one given was the end piece that was on top. I’m like I specifically asked you not to and saw you watching me watch you. I’m not gonna make a fuss because it’s too much work I just won’t eat here anymore. Like I’m on a month diet for an even then would be back to $35 medium pizzas from here but now I’m over it. This is disappointing and it makes me not want to even eat the slices I bought because I feel some kind of way. I’m sure they’ll be fine because the food is good, I just won’t be supporting.

Slice House probably has the best pizza here in Walnut Creek. This is the go to stop when not sure what to have for lunch. Purple potatoes and chicken bacon ranch are my favorite

Have only tried the thin crust so far and it is really the best crust I have had- crispy yet chewy, thin, light and not burnt. They also have a very delicious vegan cheese and vegan pepperoni. Staff very friendly as well and they seem to enjoy working there

If you're a pizza lover, Slice House in Walnut Creek is a must-try. The menu offers an impressive range—from New York and Sicilian to Detroit-style slices—all crafted with bold flavor and perfect texture. I had the Wiseguy slice it was absolutely on point: crispy, cheesy, and packed with flavor. Service is fast and friendly, even when it’s busy, and the location has a casual vibe that works whether you’re dining in or grabbing a slice on the go. I also loved how clean the space was, and parking was surprisingly easy for downtown Walnut Creek. Prices are fair for the quality—you're paying for real-deal ingredients and a slice that fills you up.

I wasn’t sure what to expect out of a NY pizza place in the Bay Area but this spot was pretty good and really did remind me of slice houses in NYC. Inside the counter you have various different pizzas to choose from including toppings and styles. They also do a rotating flavor of the day to keep it interesting. On my visit I tried one called the Motorhead slice which was basically a meat lovers but the ingredients were super fresh tasting and the crust wasn’t too bready. Prices here are comparable to Joe’s or Prince Street at around $6-7 a slice but the taste matches that level as well so not bad at all. Excited to have found a new pizza place nearby.
