Authentic Vietnamese Gem with a Hometown Feel
This casual bistro offers authentic Vietnamese food that truly impressed. My favorite dish was the slow braised pork ball in pork and tomato jus, perfectly complemented by a mini baguette on the side. The Vietnamese drip coffee was a delightful reminder of my hometown's flavors. The food and atmosphere both received a perfect score of 5, and there was no wait time. While the noise level was loud, it was still possible to hold a conversation.

Good BĂĄnh ÆŻá»›t, Cash Only
My experience at this restaurant was centered around a craving for BĂĄnh ÆŻá»›t. The restaurant itself is small but clean and tidy. The price is reasonable. Overall, the BĂĄnh ÆŻá»›t dish was good. However, I am a bit allergic to MSG and felt drowsy soon after eating. I haven't tried other dishes or bĂĄnh mĂŹ yet. I plan to come back.

Authentic Vietnamese Food with a Few Caveats
I visited this restaurant without any prior plans. It's run by Vietnamese staff; one speaks limited English, while the other is proficient. The menu has numbers, which makes ordering straightforward. Although it states 'cash only, ' I'm unsure if this is strictly enforced. The food is authentic, no-compromise Vietnamese cuisine, which might be polarizing for some. However, the effort and depth of flavor are undeniable, and the value for money is excellent. We visited with a baby in a stroller, and it's worth noting that the entrance is narrow and has steps, so keep this in mind if you plan to visit. Additionally, there are many homeless people nearby, and the area can be a bit smelly. The restaurant itself is relatively clean, but the interior is not spacious.
