During my visit to Sourdough & Moore, I noticed a cafe with an interesting name as I walked to my car by the name of Sine Wave Cafe. So, I looked it up. The place had only been open since last May and seemed to have some major surfer/beach vibes. It was also dog friendly. Since our usual, Bay Park Coffee doesn’t open until 730 on Sundays, JJ and I decided to check the place out. I figured that 7am on Sunday’s in OB would be pretty mellow. And turns out I was correct. I easily found parking on Santa Monica Avenue, a few spaces down from the Post Office.
In what would be…at least to me, a quintessential location for a cafe in OB…tucked between a Smoke Shop and a Psychic, Palm – Tarot Card Readings Shop is Sine Wave Cafe.

We walked in and the very nice young lady working greeted us; came and gave JJ a treat and some “pets”. She took my order and we headed out to the front patio.

On the way out I noticed this framed photo and I asked who this was.

She told me it’s the owner’s dog and his name is….wait for it…Sammy! And suddenly I was getting my own personal “sine wave“! Cause you know why, right?
I had ordered a Cold Brew ($5) and a “Simply Avo” ($7.50). There was a Deluxe Avocado Toast which had Arugula, Feta, Sun Dried Tomato, and Two Poached Eggs, but that just seemed like too much for me at 7am. Anyway, I waited for my Cold Brew and then headed out to the patio.

Fairly light, smooth, and easy to drink. This was fine.
JJ was enjoying things as two customers came to play with him as they waited for their coffees, so he had a blast.

The young lady brought out my Avocado Toast.

This was pretty good. I enjoyed the chili flakes, which gave things a nice spice. There’s an acidic element to the mashed avocado; I’m thinking lemon juice. The avocado was fresh, no brown spots, easy to eat. The bread had been nicely toasted, great crunch, adding to a nice textural contrast. Better than some ten to twelve dollar avocado toasts I’d had recently!
This is a nice neighborhood place. And JJ seems to really enjoy OB. So, we decided to head on back on a recent Sunday.
I had seen an interesting item on the menu during my previous visit. Sine Wave has something called a “Brekkie” Calzone ($8) on the menu. So, I wanted to try that. When I ordered, the gentleman working told me “good choice, we have a current special…coffee and calzone for ten bucks!” Nice!

Basically, the same drill. I waited inside for my cold brew and then headed out to the patio with JJ. And the gentleman kindly delivered the “Calzone”, which I thought looked really light in color.

When I’m thinking of a “calzone”, I’m expecting a nice crisp, brown crust. This was doughy and soft; except for the folds which were really hard.

This was filled with a generous amount of egg and a layer of bacon that was a bit too chewy for my liking. The egg also didn’t seemed to have been seasoned, so the tangy marinara came in handy.

This was fine for five bucks; but I don’t think I’d pay eight for it.

On this morning, I decided to take JJ down Santa Monica Avenue to the waterfront. Things were a bit odd as I didn’t notice, but there were some folks camped out near the library. Though there’s always something interesting to see in OB.

Though things started getting a bit “grittier” near the CVS with several more folks camping out and asking for cash.

And we needed to really watch our step as the sidewalks in the area was covered in, ahem…”urban landmines” get my drift? The size of which seemed to make it of the human type.
Things cleaned up a bit as we got to Abbott Street and walked along the walkway a bit. It was a very nice morning.

The folks at Sine Wave treated JJ so nicely, that I think I’ll be back….probably for Avo Toast though…..
