We were walking by having dropped our cat off at the ocean Avenue veterinarian and saw this little casual non-descript restaurant serving ramen. We were hungry so after looking at their posted menu decided to give it a try. We were very happy that we did.

We had the tan tan ramen combo with pork belly (b11) and the lobster pork tonkatsu ramen (b5). We were stunned at the quality and quantity of the ingredients. Both bowls came with a large block of roasted pork with carmelized edges showing their roasting marks. It was so large it was hard to eat but the flavor were a salty smoky taste that was delicious. The large thinly sliced pork melted in your mouth and was the size of a pancake!! Both dishes were great but the lobster tonkatsu soup had an edge over the other bowl. Medium spicy was perfect but probably leans towards mild.

Service was good and the decor is not much to look at but given the price, quality and portions, this is an exceptional place!

Updated review 3/11/2022: 21 Taste House is still my favorite ramen restaurant in this part of the city. Their broth is cooked for 10+ hours and I can taste it. The things I love about 21 Taste House are: no 30 minute + wait times, food is always awesome and a fast kitchen. Tonight I had the original pork flavor tonkotsu ramen $13 and chicken karaage $6. The pork pieces were tender and very good. Egg was jelly. I did enjoy the chicken karaage. Great job everyone at 21 Taste House.

Original review: Chinese owned Japanese ramen restaurant. I was pleasantly surprised. The chef spent a lot of time on the broth and it shows. The flavor reminds me of the good ramen joints in Hong Kong. Well, if I compared this restaurant to the ones in Japan, it is a couple of notches below those, but this place is better than some places in San Mateo and SF Japantown. I had their lobster pork flavor tonkontsu ramen $12.50. It had three generous pieces of roasted pork, ground pork, pork shoulder. It was perfectly cooked and very soft. The black fungus was mixed with cabbage and lettuce. It is not typical to have cabbage and lettuce in ramen and it doesn't mix well with the broth. The 1/2 marinated egg was delicious. Minor tip: skip the shrimp temura $6. The batter is not light enough. It is too bad no one else was dining tonight indoors. The ramen was spot on. I will be back.

Super friendly staff, and they were also very generous with the portion size. The ramen tasted amazing and the seating arrangements inside were setup nicely and more private. The music was also really nice, felt like a very early 2000s type place!

Simply put, it hit the spot; delicious. The service was great and the food was served in a very reasonable amount of time. Smaller place, more of a setting for small groups, couples or takeout.

Their ramen is so good that I wish I’ve known this restaurant earlier! Best ramen I’ve tried in SF.
The portion is great!
The service is very good!
The taste of food is very good!
