About This Spot
Nestled along the quiet stretch of Pasadena Avenue, Cos & Pi welcomes you like a familiar neighborhood spot where mornings gently unfold at their own pace. The space hums with a relaxed energy—bright but unhurried—inviting anyone looking to linger over a thoughtfully prepared brunch or breakfast. It’s the kind of place where the scent of freshly baked bread mingles with faint hints of espresso and toast warming on the griddle, offering a comforting backdrop to easy conversations and quiet moments alike.
The rhythm here matches the neighborhood’s laid-back vibe: casual enough to feel welcoming in sneakers, yet with an attention to detail that reveals itself in the friendly smiles at the counter and the care poured into each plate. It’s a haven for those who appreciate hearty, honest American fare without the need for fuss, where every dish feels made with a genuine touch—from the crisp, bright pop of lemon on creamy avocado fries to the satisfying warmth of perfectly cooked eggs and house-baked buns that cradle juicy burgers or inventive sandwiches.
Visitors find joy in familiar flavors elevated through subtle creativity—those small flourishes like the intriguing blend of cheeses on a burger, or a zingy homemade hot sauce that ensures every bite stays interesting. Whether it’s a leisurely brunch with matcha latte in hand or an early breakfast before starting the day, the atmosphere encourages comfort and connection. The places where the right balance of fresh ingredients, genuinely friendly service, and an inviting pace come together to create something quietly memorable.
Cos & Pi reveals itself as the kind of spot that feels discovered rather than advertised, a little gem where locals pause to savor familiar favorites or try a new twist among casually curated ingredients. It’s less about rushing through a meal and more about settling in—embracing that soft, steady hum of a South Pasadena morning shared with good food and gentle company.

If you’re looking for a fresh hearty American breakfast this is the spot. You can taste the freshness in every bite of their food. We got the Turkey club, breakfast croissant and avocado fries. The portions were all fair and very filling. The avocado fries was my favorite, you can tell they make it all in house and the acidity of the lemon kept every bite refreshing. One downside is the price is a little too high for the type of food. If it was 5 dollar cheaper overall I think I would have been happy.

Cute little brunch spot in South Pasadena. It was easy to find street parking, which is always a plus! The food portions were a good size, filling and tasty.

My go to spot for a great breakfast or lunch! Literally everything I’ve ever gotten here has been fantastic. The breakfast burrito, avocado toast, spamwich, and any of the burgers are untouchable. The hash brown au gratin is a must order. The service is always friendly and helpful as well. Highly recommend :)

The food was pretty delicious(You have to order first before you can sit at a table). The food took a minute but it was nice and warm as it was coming out.

Great hole in the wall! What a wonderful spot to stumble on. Lovely food, best brunch in Pasadena. Perfect Matcha Lattes.

Amazing food. Small, cozy little spot that is all about making great tasting food. Order at the counter as you come in, find a seat at either the counter or one of the few tables, and then experience food that tastes like it came out of a home kitchen. Every flavor is distinct, the freshness of the ingredients is apparent, and the overall satisfaction of eating is through the roof.

Had the BLT w/bacon and it was so big! Really delicious. The bread was soft and fluffy and the bacon was really thick. The hash brown cannot be skipped. It was so good! We kept coming back to that over and over. Husband got the "spam" & egg sandwich and enjoyed it. We also enjoyed the garlic fries. Parking is only available on the side street and good luck finding a spot. The staff are super nice and our order arrived quickly. We would definitely go back.

I hadn't been here in a while. I had forgotten how delicious the food is. I had the breakfast burrito and it tasted amazing I especially love the green salsa they give with it. I will be back. I also like that they have parking in the back
