Came here for a quick breakfast since we needed to head out. Street parking only. The staff were super kind and helpful. We wanted to get some steamed milk for my kiddo and they were so kind and just gave us a small cup! We also ordered their avocado toast and veggie calzone with cold brew (combo is $10 if I remember correctly). Both were great, but if I had to choose definitely go for the avocado toast. Cute small area inside with some outdoor seating. read more

I love supporting business owners that aren't chain and I love the ambiance at this cafe. I got the everything bagel and chose the tomato jam. There is another option of jam but totally forgot what it was. Wait didn't take long and I really enjoyed my food. I also ordered a London fog and it was . Owners are friendly and I definitely recommend. WiFi available available Indoor seating 3 tables of outdoor seating Free parking outside but with time limit (note: beware of getting ticketed if staying more than time allotted where you park as I've seen employees marking the tires of cars) No bathroom inside but if the library is open just go across for it or possibly CVS from what I heard They also offer prints from locals and I have actually bought one for my room from IG @rawoceanphotography and noticed that they do hold events sometimes at after hours. 10/10 recommend this business and would recommend to my family or friends or take them here if visiting and in area :) read more

This place is a cute new coffee shop tucked away in the school zone section of OB. I came here on a Sunday after pickleball and needed caffeine and food. I got a cold brew with cinnamon cold foam and it hit the spot. Their main food/ signature seemed to be their toasts so we tried two: Avocado toast - a bit pricey but the bread was amazing and the eggs were excellent! They had cool golden utensils to make it a bit easier to eat. Egg salad toast - this was recommended and I see why! A very comforting balance of savory and fresh flavor, not too heavy not too light. A few people working on their laptops and a few tables outside as well, a very chill spot. read more

While departing the OB neighborhood on a couple of occasions earlier this summer, I noticed Sine Wave Cafe which was located on the same block of Santa Monica Ave as the US Post Office. The cafe occupied a middle suite between a smoke shop to its left and a psychic to its right. Diagonal parking spaces were available up and down both sides of the street. Countertop seating was on the right side while several tables were set up on the left side if you wanted to hang out. There were also two outdoor tables on the front patio. During the time of my visit, the menu consisted of calzones, oats, and toast for food. Coffee and tea were the primary beverages. It was near closing so I ordered a Breakfast Calzone and a Matcha Latte. Egg, spinach, mushroom, and mozzarella made up the filling inside the pastry. A small cup of tomato jam was provided on the side for dipping. The latte was served cold with ice. The calzone was rather small for the $5 price. The kitchen initially underheated the product and took it back from me for another round in the oven. As compensation for the trouble, they offered a complimentary brown butter chocolate chip cookie which was a nice gesture. The cookie tasted better than the calzone, perhaps because of my sweet tooth. The green colored drink was fairly standard and had a good amount of matcha flavor. read more

This is a terrific locally owned coffeeshop. The shop has a lot of good stuff to offer. I had an iced coffee with milk and a couple of their breakfast calzones: one with bacon on and eggs and the other with veggies and eggs. You can get a regular coffee and two small calzones for $10. The iced coffee was great. The coffee offered a great medium coffee flavor and was smooth and rich. The calzone are made in house by the owner. I like that they are crispy in nature and filled nicely with their tasty filling. I enjoyed both of them, but I was most fond of the bacon and eggs given the savory flavor. Make sure you try their tomato jam. It goes very well with these little calzones. The service was very friendly and welcoming. They offer inside and outside seating. They also over baked goods and a variety of different toasts. read more

Sine Wave Cafe - Coffee & Tea Near Me - San Diego, California

In a neighborhood with probably the highest per capita good coffee shops (no starbucks, ye!). Sinewave found a niche. Millennials are older now, they have corporate jobs, own asset and have child and also love midcentury decor. Also too old for loud music. This coffee shop does it all, mcm checked, subtle background rock music checked. Excellent coffee checked. So when i want a quiter work morning, this cafe is excellent in its warm woody decor. I put on the headphone and i feel like i am home . read more

Great place! Drinks, food are both fantastic. Very welcoming! Met owner and his father.

We ate here twice while staying in OB for a staycation, and I can't wait to drive back down to not only eat here again, but sit and soak in the chill vibe. It felt like home the second we walked in, and they remembered us when we came in the next day. I've already tried to replicate the toasted coconut cappuccino at home, but I just can't do it. The toast with tomato jelly was a suggestion that was not on the menu, and I've been craving that ever since as well. Every ingredient was so fresh! The food was made with such care and attention to detail! May you be mobbed every day of the week, Sine Cafe! See you again soon! read more

Really cute new coffee shop in OB! Has a ton of seating inside for working remotely. Service was so great and they even gave my friend a free coffee that they were testing out recipes for! I was excited to see the breakfast bacon calzone on the menu because I'm always looking for unique food items at coffee shops to fuel me while I'm working. You could taste the herbs in the crust and the tomato jam on the side was such a fun, different sauce choice to pair it with. Definitely recommend if you're in the OB area! read more

Sine Wave Cafe - Breakfast Bacon Calzone with Tomato Jam - Coffee & Tea Near Me - San Diego, California

Came in to study while my friends did some work on a Friday morning. Maybe the best playlist i've ever heard in a coffee shop, super cute and classic decor, very good coffee and great service. I didn't get food but my friend got a calzone and loved it, and the food that the people next to us were having looked delicious, the banana bread in particular smelling amazing. I didn't get the baristas name but he was super friendly and even offered me a complimentary coconut coffee drink that they were workshopping as I was about to leave and it was delicious. I hope this place becomes a local staple, I will absolutely be back. read more

I LOVE this new spot in OB and it's definitely worth checking out if you're looking for a cute cafe. I came in on a Friday morning to get some work done and there was plenty of open seating inside! I got an iced latte with oat milk and honey which was reasonably priced and my friend got their breakfast calzone which was only $5 and the perfect snack. We stayed for around 2 hours and got some work done and I will definitely be returning. I loved the playlist they had on and the employees were super nice and seemed excited about their new spot. They've only been open for about a month so it still felt like a hidden gem, but I'm sure they won't stay secret for long! read more

I ordered a hot decaf oat milk latte with the brown sugar vanilla flavoring, and it was DELICIOUS. I primarily went to this cafe to study, and the vibes were perfect for it. They had nice background music playing that was easy to ignore. The WiFi was super fast, and the password very tasteful (it's by the door, by the way). There were loads of outlets close by to most tables. Each table was the perfect size for a laptop, or for two people wanting to catch up and chat. I stayed up until closing, and they didn't bug me to get out; instead, they offered me some kind of in-house made chocolate bread as they were going to be throwing it out, and didn't charge me even when I offered. If I'm ever back in Ocean Beach, I will definitely be returning. Thank you for the great find read more

Finally, a fantastic coffee shop in Ocean Beach!! I'm from Seattle originally, so I have pretty high standards for coffee. I've been splitting my time in OB for 10+ years and have never enjoyed any of the coffee shops around here. Sine cracked the code here! I ordered my usual drink, iced oat milk latte. First sip was perfection. Smooth, creamy, flavorful after taste but not bitter at all. Definitely will be back! read more

Can't say enough good things about this place. Their coffee drinks are so delicious and they have an amazing gluten free bagel & lox. Tons of other food options as well.
