Saw ad on extreme pepperoni pizza here. Well it's not very extreme like the ad. A bit disappointed. Pizza sauce n dough were ok. If it's your first time be ready for Hot and Cramped seating. Girl working the counter was very nice and courteous..not going to be a Favorite on my list. read more

The last Saturday of the month they have this horror pop up very cool didn't know about this and the normal wait time got pushed back to an hour . Wasn't mad about it , gave me more time to explore the pop ups and the surrounding places . When I got my pizza it smelled so scrumptious I got to the car and dug right in . I got the Marsala pizza it was delicious and the smell alone is captivating I also tried the wings and those are definitely worth a trip alone so juicy and the buffalo sauce had the right kick ! The staff was very helpful . I will definitely be stopping by again when I pass thru read more

This restaurant was incredibly clean, amazing customer service, and the food was spectacular; I was pleasantly surprised! Isabel took care of us so well and was tremendously kind to us, even though we felt unsure about what to get she was patient and made sure we were comfortable! 10/10, would definitely come again. read more

If there was any way I could give this more stars I would. Walking in the theme and esthetic caught my attention right away. The horror theme was captivating and they played classic old scary movies which makes it very nostalgic. When ordering I was greeted by Mathew working in the cash register and his service was impeccable. He was very welcoming and made sure everything was good. Now the food; idk what they put into it but honestly after being at several pizza places I have to say this is by far the BEST and I quote the best pizza I have had and want to give a huge shout out to Isabelle and Alec for making the pizza cause it was a busy day when I went in and they were able to get my pizza out on a good amount of time. Definitely recommend coming especially if you're into horror and good quality pizza. read more

UPC has hands down the best vegan pepperoni I've ever had. It kinda does the little cup thing that real pepperoni does and gets kinda crispy on the edges which is the thing I miss the most. It's pretty spicy too which is an absolute chef kiss (though a little spicier than my midwest-born husband enjoyed but he powered through). The pizza itself was amazing - a nice chewy thin crust with a slightly sweet sauce and tasty cheese. 10/10 read more

This is an awesome place. The cool dark atmosphere makes for a really nice cool down spot during the day. We had a pepperoni pizza and some stuffed knots, food was amazing and service was even better! read more

Excellent food and service. The price was reasonable and the food was delicious. My wife is has celiacs and we ordered the gluten free option to give it a try. It was so good we ended up ordering an other one to go and a regular pizza for my daughter and myself to share. As for the ambiance we loved the horror movie theme along with the music to go with it. We will definitely be coming back for more. read more

This was a stereotypical college pizza joint, the food was delicious. Service was excellent and we will definitely come back if we're in the area! Inside is a bit dark and mysterious, but we ate outside on the picnic tables. read more

We Love this place. The goth/horror theming is perfect and the vibes are immaculate. The pizzas are also great and everyone is very friendly. This is our new favorite pizza place. read more

Pizza was disappointing. I first came in here for a slice of pizza and it was super thin, cheese was not even melted and it overflowing with tomato sauce and 3 pieces of pepperoni. I wish I had taken a picture of it before turning it in and asking the workers if they had thicker crust. They told me their pizzas are all thin but that if I ordered a personalized pizza they could make the crust thicker. So that's exactly what I did. However, it wasn't the best pizza I've had. Nor was it savoring. Don't really recommend this place unless you're into tortilla looking pizza. read more

Best Vegan Pizza! Highly recommend The Supreme! Love the Pepperoni Vegan as well! Only suggestion ask for it crispy. The crust is delicious. read more

Bit expensive. Food was pretty good. Service was okay. Ambiance was cool, they have this horror theme going on.

It's my 1st time trying this UPC location. I ordered 2 medium pizzas by phone. When I went to pick my food up, there was no hello, smile, or welcome. I made the initial contact by saying hello, and I have a take out order. He charges me for my food and gives me my 2 boxes. I asked for napkins, and he said to grab them at the table. Before leaving, I checked my pizzas and saw the toppings were skimpy. Especially on the mushrooms for the veggie pie. The pizza tasted just okay. I spent about $14.00 each for the pizzas. Lil Ceaser's have more toppings and reasonable prices and taste better. I give this place a 1 star . It's a pass for me, Yelpers. read more

This was my favorite pizza place but I think they changed owners because the recipe is different :(

Order personal pizza , Burnt dry ass pizza I dont understand why give out an order like that . Not going back

Usually when restaurants go all out on a theme, the food is marginal, but this place makes me eat my words...and their fabulous pizza bombs, delicious bread puffs full of sauce, cheese and pepperoni! I will definitely return for the pizza. Fun horror movie elements inside, friendly staff, a winner! read more

Pretty rad place! Came all the way from Brea because this popped up on my Instagram The pizza was really good and made fresh!! As someone who loves horror movies having a horror movie themed pizza place is rad! We got the Hannibal pizza (I got pineapple and my half) and it was soooooo good!!! The service was fast and friendly! And I love the horror movie posters, and vibe of everything nice little hole in a wall! read more

Went in today around 9:20 pm. Me and my boyfriend were trying to decide what to get and from the start the cashier at the front was extremely rude and impatient with us. We took a little bit deciding what we wanted to get and the entire time the guy was sighing and just nodding his head. He then told us that they were closing in 30 mins which we told them okay and we tried to rush and get our order in. We wanted to do a large pizza, half "Terrifier" and half pepperoni, but he changed our order and said that he would do half terrifier and half of speciality pizza they had but with no bell peppers so I was getting the pepperoni in my pizza that I wanted. We also ordered 8 of the pizza bombs. We waited 20 mins for our order and when we came back home, he gave us a completely wrong order. The pizza ended up being a whole pepperoni pizza with half jalapeños which made absolutely no sense and nothing like we ordered. AND on top of that we only got 7 pizza bombs instead of 8. He charged us over $40 for food just for him to get our order completely wrong and skimped us out. Definitely did us wrong because we took a while to order but you had half an hour until you close, how do u mess up that bad. This place is a literal scam and the staff are rude asf. Really disappointed and a waste of $40. read more

So I left one star because I couldn't leave 0 stars and the owner or whoever the lol boy who runs pizza slit shop called me incompetent lmao. I'm incompetent but you can't even put salt and pepper on wings and throw in oven..you don't know how to put cheese on the WHOLE pizza, maybe you are just slow or cheap.. idk But I do know you will be reported over and over to BBB if you throw out another insult because I ordered for alot of ppl and they couldn't even eat it so they will be reporting too. Learn how to cook..even college students cook better than your tasteless shit shop. And grow up. Brad is your name right? Need to know who I will be reporting if you disrespect a customer again Loser read more

I like the variety of the vegan options and the quality of what I have tried so far. I also like that they are a short walk from UCR and open in the evening. I look forward to trying more of the vegan pizzas in the future! read more

The really dope thing about having some local pizza spots is that it makes them highly competitive and that's very much shown in the ingredient quality, the cook, the sauce, and the actual assembly of the pizza components. While this isn't my favorite style of savory pie (thin crust reigns Supreme here), it's a wonderful example of a business being REALLY good at something simple. The Extreme Pepperoni Pizza is absolutely a choice for folks who don't have a palate that experiences flavor fatigue quickly. There are at least 3-4 pepperoni per bite, and it is a great quality pep that they've used here. It's not too greasy, not too spicy, easy to bite, quite flavorful, and easy to chew through. While not bad, the Sausage Bombs fell a little short for me. They do come with an accompanying sauce, but the meat inside could do with a strong pinch of salt. The dough and the amount of bread to meat and cheese ratio is almost perfect. Just a LITTLE bit more seasoning would take this to the top for me. read more

I came in Friday night and it was pretty packed. Luckily I was able to find a seat. The line seemed long but it actually went by really fast. I wish I would've gotten the name of the young man who was at the register because he was so sweet. Since this was our first time here he recommended some beers and pizzas. The food took a little long but totally understandable because it was Friday night. The decor inside is really cool and is a must see for any horror fan. I ended upgetting the beetlejuice pizza and it was so bomb! I wish it did have a little more cheese though. The garlic knots are also amazing! I can't wait to go back and try different pizzas. read more

I have been here multiple times and it's been a great experience every time! I get their vegan pizzas, trying to get through the full menu lol, and best pizza hands down every time. Their garlic rolls are amazing as well! The servers have always been super nice and they're quick to get the pizzas out! I've recommended this place to multiple people and everybody has loved it. If you're looking for some great pizza at a good price I'd definitely recommend! read more

Ordered a large pepperoni pizza with extra sauce and plain chicken wings. The chicken wings were chicken sections, not full wings as advertised on the menu and extremely bland. The pizza had a good flavor, but had very little sauce like they confused extra sauce for light sauce. I am very dissatisfied with my order and if I had the time, I would have returned it all after the first bite. Update to business owners response: Your response speaks to your lack of customer service skills. Whether in person or via Yelp, I hope unhappy patrons are met with a more positive response from you in the future. read more

FOOD: I ordered the large Supreme Pizza with Buffalo and BBQ giant wings. This order alone can feed two people. The pizza was really good, I honestly had doubts about it being decent but the quality was good and ingredients tasted fresh. The wings were OK, flavor was exceptional but there was hardly any meat on them. I'd honestly would try another specialty pizza than wings IMO. They also serve alcohol! ATMOSPHERE: This is located in UCR area. I came on a late Saturday night and it wasn't too busy. There were plenty of seats and the noise level was at a good level. There's a couple of arcade games and TVs inside. This spot is a nice hangout spot for youngsters! VALUE: Service was exceptional. This place is a bit more pricey than other pizzerias. I'd come here on a day when it isn't too busy and when I'm craving a good pizza. read more

It's ok pizza. Great for the price but I didn't love it. The IE is missing a really good pizza place but it has like a thousand cheap mediocre pizza places. read more

So grateful for this company and the heart they're showing during such a difficult time in the world. Offering free deliveries for people who can't leave their home. Their actions speak volumes and they're not just a business, they're part of the community. We need more company's like this! read more

Kind of disappointed with the food and pizza. I ordered wings and I was very disappointed to see these weren't even fully coated with sauce and they seemed like old and stale Pizza was meh not much to it. Customer service was ok. read more

Good food and large portion sizes! The place had a really cool vibe if you like Hollywood terror and scary movies! Definitely recommend.

As soon as you walk in you get the delicious slap in the face smell of pizza. Brought back memories of Pizza Hut back in the early 90s. The menu has a nice variety of everything for everyone, including the gluten free, dairy free and vegan peeps. The staff were very friendly and welcoming. I had the gluten free/dairy free option and it was delicious. I only docked them one star because I asked for grilled chicken and they gave me fried, but I was so hungry I just picked it off. Either way the pizza was crispy and cheesy. My friend had the Freddy and seemed to enjoy it very much. His only feedback was the hot honey could be hotter. Overall it was delicious and will be on my list to go back read more

10/10 pizza! Great service always, especially from Matthew and Isabelle. Me and my roommate have tried everything on the menu and we keep coming back for more. My favorite thing on the there is the Tikka Masala pizza and my roommate's favorite is the garlic knots. The music isn't too loud and the decor is killer. Highly recommended! read more

Isabel is the best! Super good service & very polite to customers 10/10 will definitely come back

If you like the horror genre. This is the place to come. The food is great and the atmosphere is welcoming. The staff are very friendly and accommodating to the customers needs . The garlic Knotts will tie you up with garlic zest. The pizza bombs not only melt in your mouth but full of flavor. Both the knotts and the bombs come with a side of marinara . Tried the supreme scream pizza. Full of flavor in every bite. The atmosphere is filled with memorabilia from many famous horror films, with a play list of films and music, to fill you as you enjoy your food . read more

This place has the best customer service as well as pizza. I've ordered a few different things from here and it has never disappointed. I hope this place stays around for a long time. Walked in today for the first time and the ambiance was so chill! (Usually my husband walks in to pick up ) read more

I'd give it 2.5 stars if I could because the Hannibal Meat Lovers pizza was good but really pricey ($31 for a large). My son and I both felt Pizza Hut is better for the money. 2nd we got a buisiness card while at Creep I.E. Con and thought it was a great concept so we drove 20 minutes to check it out. We were expecting a large restaurant to walk around and see all the cool memorabilia and decorations but not even close. It is small and we looked at everything in about a minute. 3rd if it's busy, good luck getting a table. Like I said, it is small. 4th we got the buy two canned ales or IPA's and get a third for .25 cents. Not bad but the tops of the cans were filthy and disgusting. Disappointing overall because the concept is awesome. read more

Pleasantly surprised. This establishment replaced a Cajun food place that had a problem with rude employees and overpriced food. This was great service in comparison. They brought our food out for dine in to our table, friendly, greeted us as we walked in and said when dropping off the food if we needed anything to let us know. We got a half cheese half pepperoni and it was well seasoned and cheesy, although a bit greasy but that comes with the territory of all that cheese. My boyfriend got the spaghetti with meatballs, said it's a bit salty but better than the spaghetti at BJ's (his words), he'd get it again. Three lemonade options and I got the mango lemonade, very tasty. Two soda, a medium one topping pizza, and the pasta came out to about $40, which I feel is reasonable. The building needs better AC, it was way colder outside then inside, I felt like a dog panting but that's just me. Will come back, glad to have tried it out. read more
