I tried Gordon Ramsay's pizza chain, where you can eat unlimited slices for less than $20, and it was both budget-friendly and delicious

Ramsay opened his first Street Pizza location in London's St. Paul neighborhood in April 2018. The chain has since expanded to six additional locations across the capital city, as well as one in Edinburgh, Scotland. Ramsay is slated to open his first US Street Pizza location in Washington, DC.

Street Pizza has spread across London amid Ramsay's September 2020 plan to open 50 new UK restaurants — and another 200 in Asia. The "MasterChef" star revealed he wants to create a "billion-dollar dining proposition" after earning more than £15 million, or around $18 million, in 2019, according to the Daily Mail.

I've made some great Ramsay recipes (including quick burgers and pasta dishes), but I wasn't impressed with his Street Burger chain in London. I had one of the worst fried-chicken sandwiches I've ever tasted, and only enjoyed one of the three burgers that I tried.

I wasn't sure how I'd feel about Street Pizza, but the deal was too good to pass up. Ramsay's chain offers bottomless pizza slices for just £16, or around $19.29. How could I say no to that?

I was in London for a friend's wedding and decided to line up a few restaurant reviews, including Princess Diana's favorite pizza place.

As I walked up to Street Pizza for lunch, I noticed a big sign advertising the £16 deal, as well as a menu listing all the available pizza flavors. Lush foliage brought some color to the outdoor patio, which had plenty of tables.

Abstract paintings added a splash of color to the room, and the light fixtures on the ceiling reminded me of glow sticks. Ramsay's Street Burger chain is decorated with the same lights and graffiti aesthetic, bringing some cohesion to his restaurant empire.

I took my friend Ekin along to help me review the restaurant, and we decided to order the mac and cheese as well as some Summer Spritz cocktails.

Our waiter explained that he would come around with the different pies throughout our dining experience. It was time for the bottomless pizza to begin!

The cheese-less slice features charred aubergine (which is what the Brits call eggplant), plus toasted pine nuts, garlic pesto, and tomato sauce.

I love thin pizza, and the bottom of the slice had a great crispiness to it. The tomato sauce was light and delightful, I just wish there had been some more eggplant and pesto.

The tomato sauce really shined on this classic slice, and the creamy mozzarella added great texture. I really appreciated how thin the slices were — it meant I'd have plenty of room in my stomach to keep trying more flavors.

We had to wait a while in between slices, which is when I realized there was only one server passing around the pizza. Most of the tables were filled inside and there were groups sitting in the outdoor patio as well, and our server was clearly a little overwhelmed as he tried to get everyone their bottomless slices in a timely manner.

Staffing issues happen and I wasn't bothered by the wait, but Street Pizza should definitely have multiple servers on hand during peak hours — especially for the servers' sake.

Ramsay's Street Pizza offers six different cocktails — including Long Island Iced Teas and salted caramel espresso martinis — that range in price from £8 to £10.50, or around $9.65 to $12.66. Every cocktail can also be turned into a pitcher, which serves six and costs £45, or around $54.25.

The Summer Spritz — which costs £9.50, or around $11.45 — features Pimm's Sundowner, pineapple juice, elderflower, and prosecco.

I loved the color of my cocktail, which looked and tasted like a popsicle. It fit the laid-back and playful vibe of the restaurant, but I'd recommend going with Ramsay's Street Margarita instead. My table loved the cocktail so much at Street Burger that we ordered two pitchers.

Ramsay's Street Pizza has expanded its menu since my visit. The chain now offers five different styles of wings — including sweet chili kimchi and chocolate barbecue — with prices ranging from £8.50 to £31.50, or around $10.25 to $37.97, depending on how many pieces you order. The sides menu includes two different styles of fries and two types of salad, on top of the mac and cheese.

The mac and cheese — which costs £7, or around $8.48 — had a nice creamy texture and a lovely crust on top.

The pasta tasted good, albeit a tad underwhelming. I would've loved to see a few different types of cheese to add to the flavor, and maybe some heat to give the dish a little more dimension.

The pepperoni slice was packed with so much flavor. The spice from the chili flakes gave each bite a nice kick, and I loved how thick and crispy the pepperoni was — it served as a nice contrast in texture to the super-thin pizza.

Even though I still had plenty of pizza to try, I couldn't resist grabbing another pepperoni. Why not make the most of bottomless?

Ramsay's corn and chorizo pizza features sweetcorn purée, chorizo, pulled chicken, mozzarella, spring onions, and cilantro.

I loved the creativity in this pizza after trying a few classics, and thought it was another delicious slice from Ramsay. The savory chorizo and chicken paired well with the sweetcorn purée, while the spring onions and cilantro added a nice punch color. It was an unexpected flavor that I really appreciated during the bottomless experience.

I thought the slice had a pretty color (I wrote in my notes that it reminded me of Thanksgiving), and the combo of squash and blue cheese transported me to fall.

The overall taste was very similar to butternut squash soup. While it wasn't among my top slices of the day, I appreciated the creative flavor pairing.

I had a great time at Ramsay's Street Pizza. I thought the atmosphere was laid-back and fun, and it'd be a great spot to bring a group of friends, order a few cocktail pitchers, and fill up with pizza before a big night out.

While some flavors (and that mac and cheese) were unmemorable, I was pretty impressed with the Margherita, pepperoni, and corn and chorizo. Plus, you really can't beat that price.

Overall, I think Ramsay's Street Pizza offers an incredible bottomless deal, along with really affordable sides, drinks, and desserts (you can get bottomless ice cream as well!). So while I don't think I'll be going back to Street Burger on my next London visit, I'm excited to eat at Street Pizza again.
