My americano sitting there being skipped over for so long most of the ice melted.
James T.

As a consumer, you have so many choices for coffee at the ferry building every Saturday morning during farmers market. Signal coffee is good, however the attitude of their staff is baffling. I waited for my Americano for a while, many of the people in line around me already got their drinks. I asked if they called my name, and was yelled at by an older man saying they're doing the best they can and will get to my drink, and if I didn't like it, he will move my drink to the back of the line. I saw a cup with my name on it just sitting on the table constantly being skipped over. After 35 mins, I got back in line to talk to the cashier who went to grab my cup of now melted ice, and poured in a shot of espresso and said it was not okay what they did. He offered me a pastry to make up for it. Thank you for apologizing, but the behavior of the other staff is inexcusable frankly. TLDR: Good coffee, terrible experience.

I love SIGNAL! I usually get them in Alameda and was pleasantly-surprised to see that they had a stand at the Farmer's Market. They have good flavored lattes as well as baked goods. Service is always wonderful. Take your caffeine and noms and walk around the Ferry Building and Embarcadero!

Ube latte iced and cold brew

Perfect start to the day at the Ferry Building! Definitely worth waiting in line as I love their ube latte both iced and hot!

I tried out the black sesame latte. It was pretty tasty and decently strong coffee. It could have had an even stronger black sesame flavor.

Awesome coffee and awesome service! Definitely check them out if you get a chance. What a beautiful day at the Sat Farmers Market

Scone

It's been a couple weeks since I shopped at the Tuesday Ferry farmer's market. A coffee stand has occupied this space across from the Foodwise tent. Curious about this new business at the market, I looked at their menu (https://www.yelp.com/user_local_photos?userid=saJuyv784apZzH--psHZ3Q&start=96&select=_OaAyrtQxp3vsfqoU5MIIQ) and display (https://www.yelp.com/user_local_photos?userid=saJuyv784apZzH--psHZ3Q&start=96&select=y-nvgnMTx0jpXZgkrr7r3w) before deciding to try a few items. I first tried the Nitro cold brew (). It hit the spot as the slight creaminess cut the sharpness of the coffee. Perfect post shopping thirst quencher. I tried the first baked item in reheating a focaccia (https://www.yelp.com/user_local_photos?userid=saJuyv784apZzH--psHZ3Q&start=48&select=DECAJHBfgHxH20Rd2p4T3A), described as Margherita: mozzarella, fresh basil, tomato sauce, drizzled w/ hot honey. I liked the portion which is generous with the thick and puffy dough. Being more of a topping guy, this was okay and didn't wow me. The next morning, I reheated the scone (https://www.yelp.com/user_local_photos?userid=saJuyv784apZzH--psHZ3Q&start=48&select=64sKE7TwNM_d2rpxx1pDzg), which, on that particular day, was passion fruit poppy seed. The passion flavor was medium and the poppy seeds gave this a nice crunch while the scone was not hard not dry. This was my favorite of the three as it was I ate the final item as a dessert, the mochi (https://www.yelp.com/user_local_photos?userid=saJuyv784apZzH--psHZ3Q&start=24&select=lZS4fjUr2e6hfkvbMAoP4g), titled brownie filled w/ coffee creme patisserie drizzled w/ ganache & dulce de leche (gf). This was deceiving as, though looking like a brownie, this was soft and mushy with the syrup like coffee filling offering a flavor contrast. I can see this pairing well with a cup of coffee. Stopping here after shopping, there was no line so I was able to thoughly study the menu. Brendan was helpful in telling me about their background and making my drink and gathering my food. I will check them out again Tuesday. Please note that they are at this market Saturdays and Tuesdays. ** Thank you, Dani and Luna, for taking my cookies order and making my blueberry iced tea.

I couldn't find this stand. I walked inside and outside the ferry building, where is this located exactly?

We are at the Ferry Plaza Farmer’s Market on Tuesdays and Thursdays from 8-2 directly in front of the main entrance of the Ferry Building, outside, and on Saturdays to the far south end of the building, again just outside of those doors.

Cozy, upscale cafe located in the vibrant Russian Hill neighborhood…read more I went on a Monday afternoon and there was a great crowd there. Lively customers and staff, good vibes! There was a lot of natural light in the coffee shop, definitely a visually-appealing, 'aesthetic' place. I got an iced red tea and it was delicious. The tea was botanical, smooth and fragrant. Amazing experience! Excited to come back and try the coffee and pastries, which looked super fresh.

First time here for coffee! It's quite a popular shop and you see many sitting inside or waiting in…read moreline. Luckily we didn't have to wait a long line. It seems like there's also an upstairs but did not get the chance to check it out. I got an iced latte with their almond macadamia milk, and they're also so nice to do complimentary cold brew! So we got an extra drink for free. Trying the iced latte, it was pretty disappointing lol. I thought it would be similar to like a Hawaiian style latte with macadamia milk, but it was a lot lighter than I thought. It was definitely very nutty, but it also just tasted like water down latte. Honestly not much going on with the drink, but it does taste lighter in general. Crazy have to pay $1.50 more to add on this milk. Overall, its alright. I do like the natural lighting coming into the shop, but nothing too special.

such a cute place - love the ambiance. Lots of beautiful Arabic decor and art on the wall…read more My barista was so friendly and really took care to describe their specialty drinks and their flavor profiles. I was torn between Yemeni latte and their pistachio latte and ended choosing the pistachio latte but asked to make it less sweet. It was one of the BEST lattes I've ever had - very complex, not too sweet, rich and nutty. I'm so glad our hotel is nearby so I can come here again tomorrow and order this (and maybe make my husband order the Yemeni latte). Also want to try their dubai cheesecake and some of the other yummy pastries then too.

Delah Coffee is in the Financial District, one block away from a local fire station. The place is…read morepretty large with a good amount of comfortable seating. The wifi is pretty good, for those doing work there including being able to handle Zoom meeting. I've had their regular coffee and their Cortados, maybe one day I'll try one of their specialty drinks. I've had their wife range of food including their baked goods (Dubai Croissant, Almond Croissant and Cinnamon Danish) all of which were fresh and tasty. I've had tried their chicken and beef shawarmas, sharing them with friends, and those were better than I thought they'd be. This place has friendly staff, and the place has more character than the big coffee companies who shall remain nameless.
