Yupdduk Diamond Bar

"stopped by for a late lunch and the restaurant was pretty full. the food arrived very quickly and was piping hot perfect for a rainy Saturday afternoon. we ordered extra mild rice cakes and it was the perfect level of spice. we ordered the udon one and the ramen one. i enjoyed the ramen one more. we also ordered the fried assortment and my favorite was the fried sweet potato and fried pumpkin. the kimchi tuna rice was also really good. we also tried one of their specials Parmesan squid and it was my favorite dish. service was also really good and fast."

"Had a craving for Korean food and this definitely hit the spot! Stopped by for a late afternoon lunch and left with a full belly. After reading all the other reviews, we decided on ordering everything extra mild and it was a good thing we did. The rice cakes had a nice texture and the sauce was so flavorful and not too spicy. We also tried one of their specials, Parmesan garlic squid which was one of my favorites. For the non-spicy dishes, I recommend the fried assortment and kimbap. Service was quick and attentive."

"Ordered the Yupdduk Oh $22 and added glass noodles $2. The portion can feed 3-4 people.. it’s pretty big! We waited for a good 30 min.. so give yourself some time when you come here! We got the mild spice and it was still too spicy for me. I want to go back and try the extra mild which the server said it’ll be sweeter. Apparently the original is equivalent to the fire noodles. Soo ask before getting the original.. it’s not packed inside but to go orders were consistent as we were there. This store is to the left of the supermarket. Parking is a bit hard so I’d suggest just to park anywhere you can since it’s a plaza and everyone shares parking. I definitely will be coming back since portion wise was big and a decent price. Update: they have new items on their menu!!"

"If you like the chewy korean spicy rice cake dish, you will love it! It is bit spicy so I recommend ordering the rice dishes as a side. The portion was good enough to be shared and service as good as well."
