A2 Wine Bar is a wonderful addition to our community and I encourage everyone to go check them out, especially on Friday evenings when they have live music, usually jazz. The atmosphere is warm and inviting, like an art gallery, and the wine selection is well put together, with a good number of easy to drink, enjoyable, high-quality wines. Places like A2 are hard to find outside of the city, so let's support them. They're a great addition to downtown San Mateo. read more

Little confused about the hours? I've now been twice when the website and the physical sign on the door say they're open and it's crickets and the doors are locked...? Showed up for Friday most recently at 5:30, the sign on the door says it opens Friday at 5pm and it's juxtaposed by a giant closed sign right next to it. read more

They have live music on a Friday night and we happened to just walk by and decided to try one of their wine flights. Owners were really nice and a totally different vibe compared to all the other places in DTSM. Great place to relax and get a NY ambiance. read more

Cute little pop up on Sundays when the wine bar is not open. Great quality matcha and delicious desserts, not too sweet. read more

If there's anything you need to know, it's that you need to pay a visit! Wine: Balletto Estate Gewurtztraminer As recommended by Annie, we ordered a bottle of the Gewurtztraminer which was perfect for our evening. It is a dry white wine with nodes of lychee - something I would definitely try if you're just getting into wine like me. The bottle, shared by 4, was enough for two glasses each (5/5). They also have small bites that you can order, such as a charcuterie board, but I'll need to visit again to try that. Service: Went here on a Thursday night at ~9pm and was warmly greeted by Annie. Although we were a little close to closing (10pm), they still treated us with so much kindness and made sure we were comfortable. Annie kept refilling our waters/Chex mix to snack on (thank you once again!) (10000/5) Ambiance: Low-lit, warm, and a mixture of modern rustic/industrial/Japandi interior with art displayed along the walls - this place nailed the classy vibes of a wine bar. It is a little on the smaller side, but it is a great place to have a conversation/catch-up as it's so cozy in here. (5/5) That being said, I would arrive a little earlier to secure a spot if you're planning to have a larger group (most tables sit 4 as a standard). Parking: Best bet is to park in Main Street Garage as it is the closest one by A2 as well as one of the bigger parking garages in the area. Ever since DT San Mateo closed B Street off to cars, street parking has been tough! They have live music on Fridays, and sometimes Saturdays, so I will be visiting again to see that! read more

Totally unacceptable to charge me $20 for Chianti at a private event (a school parent night) and serve it in a plastic cup. When I asked for a wine glass, the server said "we are worried glasses will break." This was a school parent night. If you are worried glasses will break, then be in another business. I will never come here again, and neither should you. Beyond that, wine list was pedestrian and charcuterie unimpressive. Foghorn and other places are 100x better. read more

What a lovely place! I love the ambience here. So cozy and inviting. Was greeted by Boynton who was friendly and kind to us! He was chill and had great knowledge about the wine. Great service! We each got the white classic wine tasting flights as well as the bubbly flights. Love it! Great wines all around. I also love that we were given Asian party snacks on the side. We needed multiple refills because it was so good! They have food selections if you are also hungry and they look amazing! Would definitely come back. Again shout out to Boynton again! read more

An aesthetic new wine bar in downtown San Mateo. From the moment you enter, you're warmly welcomed by the two owners. I really appreciated the aesthetics, the seating arrangements, live music, and ambiance of this place. They chose a neutral decor with plants and art pieces throughout. The wine selection may be smaller than other wine bars, however everything was well curated. They gave generous pours and were very thorough on educating us on the wines we chose. I'm a club member at multiple wineries in Napa, and I was even impressed with their selection. They also have charcuterie boards made to order. Excited to try those next time we visit. Hours now are 5-10PM and I was told they are considering outdoor seating when it's warmer. They also have a private room that they plan on renting out for events! read more

Yelp said they were open till 10 pm. I walked by at 9:15 and a worker was inside with a projector screen watching a movie with a dog roaming around and the place was closed . Totally ridiculous! If you want customers , you need to be accountable to your hours of operation! read more

Popped into A2, a new San Mateo wine bar that is in its soft opening. The space is nicely renovated and centrally located on B Street, next to Philz and across from Kajiken. It used to be a flooring company. We were the only ones there on a Thursday evening, so they really took care of us. Menu is still in progress -- they have a selection of wines (still in flux) and snack/charcuterie boards. Great addition downtown! Hopefully they have an official website or social media presence soon for hours, menus, etc. read more

A2 is a hidden treasure in San Mateo. Once I walked in, I felt so comfortable, cozy, and relaxed. The wine is good. It is a perfect place to chill. Annie (the owner) is so nice and friendly. They also have a live jazz performance on Saturday evening each month. It is definitely a cool place to hang out with friends. Here are some photos I want to share. Please come to see Eve'Jazz Quatet performance on Saturday evening. They are awesome!!! read more

I went there with a few friends during a night with music performance. We enjoyed the music performance so much! Friendly host. Cozy feeling. read more

My friend suggested we check out the soft opening of this wine bar, A2. We were the first to arrive in a rainy night so we got VIP treatment! There was an organic wine that I enjoyed (a bit too much). The wine bar also has a private room that can be rented for events or karaoke The owners are so nice and shared that it had taken 9 months of renovation and waiting for the city to let them open. They even brought in consultants to make sure everything from the wine to operations is on point. It's hard to run a small business these days so I'm rooting for them! #winebar #femaleowned read more

This place was a pleasant surprise! We were waiting a while for our original dinner reservation and decided to get a drink here. We tried a few of their wine flights and they did not disappoint. The serving sizes for wine flights were bigger than expected and tasted delicious. Annie was very informative, friendly and made our entire experience one to remember! The charcuterie board was amazing and the goat cheese with blueberry jam was definitely the star of the show! We begged Annie for the recipe lol. The place itself was very cozy and clean. Great place for a romantic date or a night out with the girls! Thank you so much Annie! read more

I went here randomly last night for a girls night. We were walking in downtown San Mateo and found such a cute looking bar for us to hang out. They have wine and charcuterie. The wine flights are very generous, and the combinations for the charcuterie were amazing. Our favorite was definitely the goat cheese they have that comes with jam. We were able to meet Annie and she was so sweet, funny, and wonderful. She loves what she does. read more

The exterior of this lovely little wine bar belies the beauty of the artwork and clean, relaxing feel of the seating inside. There is a tasty private label rose that we tried they had a nice floral, sweetness to it, but what really knocked my socks off was their sangria. Unlike a lot of sangrias I've had in the past, it was not overly fruity or sweet, but had a very smooth, easy to drink, refreshing flavor--almost like spiked spa water. We will be back to check out the live jazz they have on Fridays. read more

Good vibes, good company, great wines! Definitely the perfect place to unwind after work.
