The service was fast and fantastic. The dishes were all very yummy. The guests ahead of us and the one behind, were all regulars and they were raving about the food and what they always get there. We weren't disappointed at all. There's outdoor seating as well in the rear of the building. They don't overcrowd the space either, they have a waiting line out front and the host takes each party inside to stay on top of the flow. Very considerate and they move very quickly, taking your order at the entrance counter, and also with bringing out your food to you. Highly recommended!
My go-to item from this place has usually been the corn tostada but they didn't have that at the moment (which I missed dearly and hope they bring it back soon) so I decided to try the waffles this time. The waffles were crunchy and fluffy. I only used a little bit of butter and syrup since the berry jam was sweet enough to complement the waffles. I appreciated that it was filling but not super rich in sweetness. The garlic fries were also amazing. They added plenty of minced garlic, which really gave the fries a nice garlicky flavor. My boyfriend got the breakfast plate and he said the highlight of his plate was the hash brown au gratin.
Everything I have tried on the menu was delicious! The pirate burger may be my favorite. The avocado fries were really good and enough for two. All servings are on the larger side. The turkey sandwich is huge and very flavorful! The breakfast croissant with eggs (I got mine over easy) was also great. Overall, this is a place is a must try. Side note: orders are placed before you seat yourself.
Wow their croissants were amazing! We had the Salmon one and the Cos&Pi speciality one. Outdoor seating was great and the food came out very quickly. Service was fine, but I don't like how you had to walk inside to get water if you had outside dining. Maybe either put another water station outside or have waiters go and fill them up. I sound really privileged and snobby from my previous sentence, but it's just a suggestion for a better overall Cos&Pi experience. Besides that, definitely a place I would like to go to again.
This place has indoor and outdoor seating. We ordered the spam sandwich, smoked salmon croissant, fries, and tostada. The fries and tostada were my favorite! The fries were extra crispy and light. The verde, egg and sweet corn on the tostada worked perfectly! And the tostada was extra crunchy! All of these items paired well with their house hot sauces. Highly recommend this cute restaurant for a brunch.
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 👍
All the good reviews from others are very true. Ordered: LABT sandwich & matcha lemonade.
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.
My favorite burger at Costco and Pi is the Cosmo burger. It's got caramelized onions, blue and gruyere cheese. The fries are super crunchy and delicious. The service is always pleasant and polite and the restaurant is clean. They also provide a water station which is much appreciated.
Had brunch here at Cos&Pi and it was great! Simple vibes inside with lots of space for us on a Saturday early afternoon. There were tables in the front and back as well if you wanted to enjoy some fresh air and shaded sunlight. We ordered the Cos&Pi Breakfast Croissant and Corn Sotto Tostada with a side of Hash Brown Au Gratin ALC. Both main dishes were delicious! Though we wished the portion size for the tostada was a little larger since it was so good. The Hash Brown Au Gratin ALC was yummy too but pretty small for the price. The service was good and fast. Lots of free street parking. Would definitely recommend for brunch! Can’t wait to come back and try some other items on the menu!
