2023 update: The new location near Nanjing Fuxing is much smaller, and the deep dish feels a little less substantial than I last remember it from the original location. (See the photo of the slice being lifted up.) Flavor still good, and this time I didn’t detect the “Taiwanese bakery butter” flavor, yay. BBP will do if you need a fix in Taipei. Old location reviews: Get your Chicago style deep dish pizza fix here! Tasty stuff; so happy to see it here. Their thin crust is also good, with a crispy bottom (although I suspect New Yorkers would debate its authenticity). You can even preorder pizzas with a reservation so that they're ready to serve when you arrive! The grand slam deep dish (No.1/大滿貫深盤) hit the spot. The butter crust has walls that are nice and tall, not quite as thin as say Lou Malnati’s, but still crusty and flavorful (and the little extra softness probably makes it easier to eat anyway). A few other notes: 1) was hoping for more cheesy goodness when pulling out that first slice, such as the experience eating at Giordano’s; 2) the sausage in the grand slam is not a uniform layer, but rather the sausage is dotted all over, since they appear to make a layer of a mix of the three meats; 3) the crust appears to use the same butter as Taiwanese bakeries do, so the flavor gives me memories of those places. (wish it were American butter - Taiwan bakeries can frankly smell too strongly of this distinctive odor, to the point of being unappetizing) 4) I actually like the chorizo on our thin crust more than the sausage in our deep dish, but it did have a good fennel sausage flavor. Still miss sausage from Chicago though. An 8" deep alone is probably good for two people. I split a 12" thin as well to start since it takes an hour to bake a deep dish, so couldn't eat more than one quarter of the deep dish. Unsurprisingly you'll pay a bit more here than in Chicago (paid ~650nt each), but as a Chicago area native, this place satisfied my craving, despite a few quibbles. 🍕 Tried more pizzas; turns out I like the Hot Summer/墨西哥深盤more than the No.1 and Veg Barrel/蔬菜, as I like their chorizo the most it seems. It also does have a little heat to it, woohoo! Their Funghi Delight/蘑菇 is not bad either, but South of the Border/南方 was tastier (chorizo!). Now if only they had spinach deep dish pies! ;)

This is the number one pizza place to go to. I usually don’t think a place is perfect but if you want get authenticity on a New York slice. This place is it. And the Chicago style deep dish is a must have too!

I really miss Chicago-style deep dish pizza since leaving the states and was on a journey to find the most authentic deep dish pizza in Taiwan. And man, I can tell you Big Boyz Pizza wins my recommendation. I've eaten many deep-dish pizzas back in the states, and I can attest Big Boyz Pizza is up there on my list! Highly recommend!

Excellent Chicago style deep dish pizza! I ordered a couple beers along with an 8 inch No. 1 deep dish pizza. The toppings were all the things: tomato sauce, mozzarella, provolone, house made Italian sausage, bacon, pepperoni, mushroom, and caramelized onion. 🤣 It was amazing! It does take about an hour to bake (the menu tells you this, and they will warn you if you order it), but it's totally worth it! I used to visit Chicago very often, and definitely very close to the real thing. You won't be disappointed! 🍕😋

Great pizza! We had the Three Knights and the BBQ Chicken and both were delish. Crust was good, cheese was great and the toppings were all fresh. I think the price was pretty on point. They even serve different bottled beers and ciders. The environment was cozy and there were some fun blues jams playing on the speakers as we dined. My only qualm was that the appetizers (onion rings and mozzarella sticks) were a little undercooked, as in the breading was too soft for being fried. Overall great though, I'll be back again!

We ordered the NY pizza which were pretty dang good already while we were waiting for the Chicago style pizza pie. But OH MY GOD the deep dish one is on another level. Totally worth the one hour wait! Definitely coming back here. 😍😍😍😍 The only thing I wish were that we had larger drinks or more options to choose from

Best pizza in town, clam and bacon is my number one option. I would definitely visit with friends next time. The reason why i give four star is because their starters are not as good as their pizzas.

Awesome crust. Crispy, not crunchy like a cookie. However, I think they forgot to add taste and cheese to it. I’ll try it again and hopefully they add the missing ingredients.

It is the best pizza I have had since coming to Taiwan 6 months ago. Both Chicago deep dish style and New York thin crust. GREAT PIZZA!

I recently tried their deep dish pizza, and teas mediocre. I can understand a 50-minute wait for such a specialty, however d portion size, taste, and even the texture of the dough from the expectation. Their thick and hard crust was less filling. I think this one didn't quite hit the mark 😉

I've been here twice, great service. I found the New York pizza very authentic and surprisingly filling. The Chicago pizza was very tasty also, highly recommend. Great selection of beers too

Great pizza but the owner has no idea how to run a business. We booked a table for 4 which was fine but when we wanted to add one more person they told us they don't have the space. One of our party went there before the reserved time. Surprise, surprise they did have enough space, but apparently just didn't want the hassle of dealing with 5 people. Anyway, their attitude was poor and I won't be giving them my business in future.

Great pizza, slightly off the beaten path. Small space for dine-in, but a pleasant environment with great aromas from the kitchen, and pool on the TV. I had the 12-inch Three Knights. Nice topping choice, everything blended well, and it had a wonderfully distinct garlic flavor, possibly mixed into the sausage pieces. Flavorful cheese and sauce balance, with a perfect chewy-crisp crust. And a hard cider to wash it all down. I've read reviews about Taiwanese leaning toward other pizza taste profiles, and I see Dominos and Pizza Hut reviews at 4+ stars - give me a break! As an American with decades of experience, who loves pizza, the big chains are so incredibly basic. By contrast, Big Boyz is excellent pizza, worth your (repeated) business.
