A local ramen joint located at the heart of the beautiful city of Castro Valley. Our broth is made in house with fresh ingredient every day and our fresh ramen noodles have these ingredients — buckwheat, barley, water, sea salt, egg and kansui.

I got a few items of food, as it being my first time trying this type of food as well as this establishment, I really appreciate the help that the nice waitress have us. She was so full of energy and made the atmosphere brighten up. Over all we ate all we could, didn’t finish all the food but then again we all got a plate and side per a person. All of which came out to about less than $20usd per a person including some type of drink.

It’s been twice I get stomach problems after ordering the seafood choices with shoyu broth. The first was from delivery which resulted in full food poisoning thus second time was in store yesterday with stomach discomfort and gas. I have eaten the same thing dish one other time no problem but it might be that the seafood is precooked and not properly reheated.

I enjoyed my Ramen choice (Black Garlic) and a (seaweed salad). I also ordered the (Chicken Rice) to share with the family that was yummy. Kiddos loved it!! Although the ( chicken Karaage) was super dry, the chicken was hard to eat, and it was overcooked, they didnt add dipping sauce either; My dogs thought they were treats. So nothing went to waste..

One thing I love about Ramen 101 is even though they are a chain, they make there own broth! The bowl of Ramen was so large that I took half home.

I would drive by sometimes and there would be a line, so that must mean it’s good, right? I’m typically not a big fan of ramen but my family wanted to eat here so I joined them and I’m glad I went. This was definitely one of the better ramen restaurants I’ve eaten at. Their chicken karaage was really good too. I want to try their unagi rice bowl next time. I saw someone else order it and it looked amazing!

This is definitely one of the best ramen places in the area; the broth especially is very flavorful. They give a small amount of meat however. There is one single room bathroom open to customers and a lot of parking in the shopping center.

Brand new ramen shop opened in the neighborhood, so my mom and I thought to give it a try. Order before you sit, pretty easy menu to follow. I got the tonkatsu ramen with medium spicy with the first fix’in. Broth was pretty flavorful, could be a little more spicier for medium and veggies were fresh. The chasiu was good, fatty, tender and tasty. Would recommend!
