Slice House by Tony Gemignani

I went to this slice house for the first time yesterday and ordered food well over $200. I came from 25 mins away only to have them hand me my order incompletely. They offered me a refund but I felt they owed me more than that since it was their error. I spoke to the manager that calls herself Alma on the phone this morning and she was so stand off, offered no empathy for the situation. Be careful here when ordering a large number of items that you have all you ordered . Apart from Vince who apologized over and over again even though it wasn’t his fault, the other server and the manager Alma appear to be incompetent

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.

Is it great pizza? Almost, but it’s about as good as it gets on this side of the tunnel.

My family and I have had slice house in the past, we decided to pick it up tonight and after tonight never again.

The place was packed, understandable it’s a Friday night. I got in line and tried to tell them that I had an order. The lady that “helped” put a hand up and with a heavy attitude looked at me like I was stupid and pointed to the other side and said pickup is over there. Then immediately moved on not even giving a chance to speak. There was no sign showing where the online pickups were. I went to where a small crowd was and hoped it was the right spot, because it’s not like I could actually ask if I was in the right place.

The order was already paid for so it was just an easy pass off and go. So we had to wait in an additional line. When we finally got up to the front, the guy just handed it to us. No verification or anything. So she literally could’ve just passed us the pizza.

I asked for some ranch and he said he would have to charge me. I figured ok normally side of ranch is like $0.50 but nope, $2.50 for 3 tiny sides that aren’t even filled up all the way. He threw them on top of the pizza not even giving a moment to grab the pizza instead already beckoning the next person.

This place has gone downhill so bad. It’s way more expensive for mediocre pizza that used to be phenomenal. If I really wanted a greasy pizza I could’ve just gone to Costco and at least be treated like a human.

Overall a terrible experience with pizza just as bad.

Some of the best pies you can get anywhere, ordering by the slice is nice to get a variety, and if you can wait, order a full pie for fresh top quality.

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.

One of the best pizzas I have ever had and delicious wings

Don’t depend on this location. Their estimates are extremely off and they routinely need more time than they say to make your orders. The food is great, but this location clearly has issues with organization and staffing.

Order pizza by the slice or whole pie
