Super Duper Burger@Lower FIDI is located on Mission between Spear and Steuart streets not too far from YMCA “Barcadero,” according to my experience, should be regarded of one of the best out of its 10 locations in The City. Super Duper Burgers was founded in 2010 in San Francisco’s Castro district by Adriano Paganini with co-founder Eddie Sarti who have a joint vision to improve both quality and service of fast-food burger in the Bay Area. The company focuses on qualitative, locally sourced, and fresh ingredients, well cooked with a mission to provide a fast-food experience with “slow food values” and the fast-food chain has since grown to numerous locations beyond The City limits across the entire Bay Area from Napa, Concord to San Ho. Lower FIDI is conveniently connected to all transit and just one block from the Ferry Building. The location is clean, spacious (indoor and outdoor seatings) and accommodated with quality food and more importantly, a super friendly service team who will greet you as soon as you walk in. My favorite order off its menu is its Chicken Sandwich with Chipotle Aioli on a fresh Ciabatta Bun with a small addon of Jalapenos for just $11.50. I have (and I am confident that you would as well) have nothing to complaint except they should place a “cookie jar” at the cashier so customers could effective place their appreciation tokens as quite often orders are placed via self-ordering kiosks. PS Regrettably, Super Duper locations on Market Downtown and Metron where I used to go have declined in both food quality and service. Service is terrible to no service at all ppl constantly chatting or joking around among themselves. Its burgers are not well cooked (pinkish and “smooshy”). The same chicken sandwich is terribly prepared and lacks proper and quality ingredients at Metron that would make Lower FIDI a five-star location.

I got the super burger. The meat had a nice crisp edge, was juicy, and well seasoned. The rest of the burger was very well balanced.
The garlic fries we’re very flavorful though.
We shared a cone with our son and the chocolate soft serve was a nice surprise.
The staff were friendly and helpful.

Amazing burger and garlic fries. Even well done the patties were juicy and full of flavor. The garlic fries were perfect and of course, enough garlic to hit the spot. The lemonade was definitely home made and unique.
We are from So Cal and love In-n-Out burger, but if Super Duper was available this would be out go to spot.
And thank you for making your food affordable and reasonlu priced in this economy.

I recently visited Super Duper Burger at 98 Mission Street in San Francisco, and I have to say, the experience was fantastic! I ordered their fried chicken sandwich, a side of fries, and a strawberry milkshake, and everything exceeded my expectations. The chicken was perfectly crispy and flavorful, the fries were hot and golden, and the strawberry milkshake was rich, creamy, and bursting with real strawberry flavor. The combination made for an incredibly satisfying meal. The service was friendly and quick, making the whole experience even better. I highly recommend checking out Super Duper Burger if you’re in the area!

Burger was moist and flavorful. Garlic fries were good as well. I wish they could have melted the cheese on the fries, but that is just my opinion. I sat in the bench seating facing the outside (and the trash) so I could see life as it passes by, unfortunately there were a lot of gnats flying around my food. I hope this was just a one off, but there were a lot. Either way I swatted them away and finished my meal. Arnold Palmer was a good drink.

Visited the Mission & Spear location on Feb 14, 2026 around 7 PM. They were out of beef, so I ordered the fried chicken sandwich. While eating it, I found a small piece of plastic film in my mouth. I showed it to the manager, but the concern was largely dismissed and the item was thrown away without any reassurance that it would be looked into.
I’m a regular at this chain and usually enjoy it, but this location was a disappointing experience

Delicious burgers! They do t have a gluten free bun but they offer a lettuce wrap. The burger is pretty juicy though so I would recommend a fork and knife. The garlic fries were delicious but heavy on the garlic so be prepared! The home made pickles were very unique and tangy. Would recommend!

My girl and I split a chicken sandwich and a super burger. Very delicious. We’re from Phoenix Az so didn’t know where to eat. Made a random stop and we’re very satisfied with our choice. Would definitely recommend to others

Tasty burgers and plenty of seating.
After ordering on the kiosk, I received my mini burger about five minutes later. It was warm, on a toasted bun, and cooked perfectly. If you’re looking to eat without human interaction, this is a place to do it.
The interior has plenty of seating, as does the outside. You can find some art and the nice signs that are standard at every location. However, it’s not the cleanest Super Duper Burgers location. I recommend sitting inside, because it’s cold outside and there are pigeons. This is a good place for a good burger.

Loved the chicken caprese, it was a whole mouth full and I couldn’t get enough of it!! The garlic fries were to die for!
And the fresh strawberry shake was so fresh and creamy. Unbelievable value and taste, and got it 5 mins
