Crema's Take

SIGNAL Coffee Roasters brings adventurous, globally-inspired specialty drinks to Alameda with creative offerings like Black Sesame and Ube Lattes that actually deliver on flavor while maintaining serious espresso fundamentals—their iced americanos are notably well-dialed in, a rarity on the island. The vibe is pleasant and approachable rather than pretentious, though the experience feels more about the drinks themselves than any transcendent atmosphere, and their signature items lean more experimental than Instagram-famous.

The atmosphere at this location was nice, the service was ok (no complaints but also nothing to rave about) the drinks though… they left a lot to be desired. My iced chai had very little flavor and my friend had commented that the mocha tasted more like coffee.

An unremarkable cinnamon roll (especially given how famous it’s supposed to be), average coffee, cold atmosphere

It’s pretty rare that I come across a Black Sesame Latte on a menu, so I was excited to see it offered here and had to give it a try. I was pleased that it still maintained a solid coffee flavor, though I do wish the nutty black sesame notes had been a bit more pronounced. My husband ordered the Ube Latte, and he absolutely loved it. Overall, our drinks were enjoyable, and we liked them enough that while we were still in town, we came back and ordered them again a couple of days later.

In SFO for a weekend and we were looking for new, unique coffee experience. Very pleased to have found Signal at the Ferry building’s farmers market! We got to try their black sesame and ube lattes (both hot). Ube latte was phenomenal - ube flavor was prominent and added just the right touch of sweetness and creaminess. I had higher expectations for the black sesame latte but unfortunately the black sesame flavor was too subtle. We must say their ube latte has now set the golden standard for us and we will return for this delicious caffeinated treat!

I love a good iced americano, and this signal location does them very well! Most shops on the island don’t seem to dial in their espresso so americanos end up pretty gross - that is not the case with signal! They consistently pull great shots, have awesome food choices, and are knowledgeable about the beans they sell. Love this spot!
