Iced banana cream matcha
Sandra V.

I came in to try their banana cream matcha. I got iced, the banana cream was delish, the matcha I usually like it stronger and felt too light for me. I also ordered their salted small banhi. It was good, the bread was fresh too. The ambiance it's a small coffee shop inside the Walnut Creek library which I love the convenience of both places in the same building. There's a few table and chair seating and more outdoors seating available. Parking is next to the building underground.

Binggrae Banana Milk

I tried the pandan and coco latte and I really enjoyed it! It was smooth, creamy, and not too sweet. We ordered delivery and it came fast and everyone enjoyed their drinks. I just found out this is a woman owned cafe so I will definitely continue to support!

Banana Milk Vietnamese Coffee & Chicken Banh Mi
Kare V.

I wanted to try the banana coffee that I heard so much about. I thought it was too much banana flavor. I do love bananas though and banana pie. I thought I would like it. I also tried a chicken banh mi sandwich. It was alright. Kibis cafe down the street makes better banh sandwiches. They put very little cilantro which was disappointing.

Croffle
Nicole D.

I love that this is located in the library! How cute! There is a parking lot that is free until 10 am which is really convenient. A couple of inside tables and bar top seats. No line on a Saturday morning but I could hear the door dash/takeaway going crazy! I ordered a matcha latte with Ube foam and it was good! A perfect sweetness and neither flavor was overpowering. I'd come back again to try a different matcha. My friend ordered the croffle and said it was crispy and delicious. Staff was very sweet and patient.

Full size grilled banh mi

Banh Minh: 4 out 5 Solid viet sandwich for Walnut Creek. Preferred the cold cut over the grilled chicken. Service: 5 out of 5 Super friendly folks working Environment: 4 out 5 Fast casual & within the library. Some seating outside.

Food Menu (August 2025)
Harvey K.

Prologue Coffee & Tea is a small café operating inside the Walnut Creek Library in downtown (Walnut Creek has two libraries). Although the location is not prominent, pictures of their beautifully crafted drinks and delicious bánh mì sandwiches have been spreading across different social media platforms. So much so that they have been featured in reporting by several local media outlets. Out of curiosity, I decided to check this spot out with my brother and a couple friends on 08/29/2025. It wasn't busy when we walked in at around noon. A quick glance revealed a space that's tiny but well organized. We were greeted by Thuy, the friendly proprietor of the establishment. Since this was our first visit, it took us a while to figure out what we wanted. In the end, we each got a bánh mì sandwich and a beverage. Pricing was reasonable IMHO (see menu pic). I had the cold cut bánh mì and an iced coffee. I gave half of my sandwich to my brother, and he gave me half of his grilled chicken bánh mì in return. Both sandwiches were delicious! The baguette was excellent. It was crispy on the outside and soft and spongy on the inside. Thuy told me later on that she gets them from Duc Huong Sandwiches, a famed Vietnamese sandwich chain in San Jose. The homemade pâté, cold cuts, and grilled chicken were all delicious, and the produce was very fresh. The iced coffee was very good as well. We chatted with Thuy extensively before and after our meal. She told us she was a banker prior to opening this café. From our conversation, I could tell she takes pride in her work. We were all very impressed by her demeanor and business acumen. Should you find yourself in downtown Walnut Creek, do yourself a favor and give this place a try. You will not be disappointed. 5 stars. BONUS MATERIAL: - You can either park at the library lot, Civic Park, or the Broadway city garage a block away. - Contactless payment. - They have limited indoor and outdoor seating.

Signature Salato Foam Latte (def get this one)
AJ S.

Took me ages to try this place. I love the salato, that's 100% the order to get and is worth every penny. I do it without a syrup, but you get a flavored syrup in there if you want it (built into the price). The Vietnamese was too sweet for me and the americano is way too watered down for me (this is everywhere really). Some of the best coffee in the area imo for the salato, nice depth of flavor and not acidic.

The outside
Cat N.

I went to the library and what a cute find that there is a coffee shop right there! The people that work at prologue are very nice as are the customers. I was standing in line trying to make a decision not realizing I was creating a line and I apologized profusely and everybody was so kind and kept saying no it's not a problem. Don't worry about it. They have so many different foods and coffee drinks. It's amazing. The coffee tasted really good and I'll have to go another time for the treats. The inside is really welcoming. I highly recommend it.

Vietnamese Iced Coffee with Banana Milk
Sara B.

Their Vietnamese coffee with banana milk is amazing!!! I am a banana lover, especially in my iced coffee and lattes. I have tried several banana flavored coffee drinks, and this one reigns supreme. They are located in the Walnut Creek library, with an additional entrance through the outdoor seating area. The shop is also very cute and offers sandwiches and desserts. Highly recommend to stop by!

Sakura Cherry Blossom Matcha
Manit D.

This place is connected to the library. They had many different flavors of matcha, I ended up getting the sakura cherry blossom matcha. I loved the sakura taste, however the drink felt watery, matcha can be better.

I stopped in Prologue because I was visiting the Walnut Creek library. I had no idea there was a coffee shop attached, so cool! I had to hop on the trend and try out the banana milk. I ordered a Vietnamese coffee + banana milk. I enjoyed it but wouldn't order it again. I think I would just get regular shots of espresso + the banana milk. The inside of the coffee shop is very cozy. They had a few tables and barstools if you need to sit down. They also have a variety of food options.

Marie E.

A coffee shop attached to a library? I'm in! I stopped by and tried the banana milk coffee along with a cold cut banh mi and both were so good! My daughter ordered an iced caramel macchiato and said it's the best one she's had so far. We were definitely impressed and plan on coming back. The only downside was the wait and how a bit chaotic it felt when walking in. I waited almost 15 minutes for just two drinks. That said, the pros definitely outweigh the cons. One of the best parts was being able to take our drinks into the library, sit down, read our books and enjoy our coffee. Win-win. Note: Only covered drinks are allowed if you plan to bring them into the library

Reminds me of this place that sold banh mi and boba that I used to study at during my student years. I saw the banh mi advertised and just had to try. They've got an eclectic mix of food and drink items to choose from: some more traditional breakfast items, sandwiches, and some traditional coffeees, and some Asian-inspired drinks as well (ube, matcha, Vietnamese egg coffee, etc.). For the banh mi, you can choose from a small or large size. Got to say, I was pleasantly surprised! Bread was nicely toasted and there was a good ratio of filling to bread. To be honest, I forgot about this place since it's attached to the WC library, but writing this review makes me want to stop by in the near future.

Don't get me wrong, the Genova's in the big (little) Dub Cee does what it can to keep up and turns out some pretty decent sandwiches. It has all the trademark imported knickknacks (biscotti, multicolored taffy in well-worn bins, boxed panettone, etc.) as well as traditional staples like wine, fresh pasta and the famed Genova's brand boxed frozen ravioli for you to take home and spoil your family with in a variety of flavors like artichoke, mushroom and even pumpkin. But it lacks soul. It lacks spirit. It doesn't have any of the flavor that the Genova's in Oakland had and each sandwich churned out is indicative of that. It's just not that good. And for a sandwich you have to wait a mighty long time for, it better be good. Real good. So, I've come to terms with the fact that I don't have a Genova's left to go to and that's okay. Sometimes it's better to have loved and lost (a sandwich) than never to have loved at all.

Now...Now I see why the Matt Cain is one of the more popular sandwiches…read more.. Me and my buddy ordered some sammies for our weekly video-game day. If you live in the Bay Area, you already know. Ike's sandwiches always delivers. I've never had a bad sandwich but personally my favorite sandwich is usually the Madison Bumgarner. It always scratches my itch for BBQ. However I recently decided to try the famous Mat Cain sandwich. I think I might have a new favorite sandwich now... The Mat Cain is heavy protein with Beef, Salami and Turkey. I think ultimately it's more Beef forward but the Salami and Godfather sauce really evolve the sandwich. If you love prime rib. Order this sandwich. If you are a fan of mustard. Order this sandwich. If you are a long time fan of Ikes and have yet to try the Mat Cain...ORDER THIS SANDWICH. Good lord is tasty. The Godfather sauce is so addicting. You think it's just a fancy mustard but then the next second you think that it's actually a horseradish. I really think the horseradish radish flavor is such a genius idea because it pairs so well with the Beef. Just like the mustard pairs so well with the Salami. Theres just so many layers to this sandwich. God. The more I talk about this. The more I just want to order this again.

Fast service and such a variety!!! Good meat to bread ratio! I did the classic Matt Cain. Very…read moregood- a bit too saucy for me so I would ask for light sauce next time but very good!

That was the main reason I ordered the hay bagel in particular. When I went there this morning, I also noticed the strawberry and pineapple flavors for ice cream. I came back in the afternoon and got a swirled cone. It was soooooo good. I can't wait to see what other flavors they offer in the future!
