Food Quality
Pros:
"Superb food traditional Japanese with a great depth of flavour."
"The food was delicious."
"The mackerel was quite good and the soup was very flavourful."
"Udon was perfectly chewy and not too dense or soft."
"The prawn tempura was phenomenal - well fried with a light batter."
"Mind-blowing udon. The beef one (niku) came with perfect slices of rare, delicious steak, and the broth was perfectly beefy."
"One of the best udon I have ever tasted in London."
Cons:
"The shrimp in the tempura was old and mushy."
"The second dish was Kamodon which unfortunately the duck was chewy and the portion was small and pricey."
"But the vegan ramen was very bland and the appetizer tasted very good but in the end the price was too high for what we got."
"The bottom of katsu was wet and sauce and was way too salty so I couldn't keep eating with them."
"The beef donburi was sadly also underwhelming. The beef had minimal flavor and had a stringy texture."
"The Udon and Gyudon are very bland, almost tasteless."
"The hot udon in soup with duck meat wasn’t really impressive especially the duck tastes very normal."
Service
Pros:
"Employees are very friendly, efficient, and professional."
"Service was great, all the staff were super nice and friendly☺️"
"The service was efficient and friendly."
"Also the staff were very friendly and though it was busy we were served fairly quickly too."
"The attentive waitress always came to replace the bottle when empty; very good service."
"Staff were quite efficient and friendly."
"The staff are friendly!"
Cons:
"The service was ok, but not great. We were not given additional water, and we had to ask for the bill multiple times."
"After waiting for 30 minutes outside to get a table, we were ignored by the servers and never got our orders taken, even after waiting for another 30 minutes inside."
"The customer service was a bit rude and uninterested which is not great given the prices."
"Service can be a little better - though the staff were attentive, they didn’t bring an item in our order but had billed us for it."
"The staff used to welcome you in and says goodbye to you on the way out, not today."
"server was incredibly rude and tempura sauce cost an extra £3.50!"
"Service was poor as the waiter gave my dish to the wrong person they had to remake one."
Ambiance
Pros:
"The decor & atmosphere is 10/10 though, aesthetic and reminiscent of Japan."
"Great atmosphere that makes me feel like I’m in Japan."
"The ambiance is very cozy and I love the open kitchen which allows customers to see how their food are made."
"The interior area is small but so authentic, seating at the 'noodle bar', you can see your udon being made."
"The ambience was really nice, it felt like we were transported to Japan."
"The atmosphere is unique and it’s lovely to see the cuisine right in front of you."
"With bar seats and a very authentic Japanese feel, Koya clearly knows what it’s doing when it comes to udon!"
Cons:
"Be aware that the place is quite small and the big queue means you will have to vacate your seats as soon as you finish eating."
"Be prepared for a cramp seatings during peak timings."
"The seats are slightly on the crowded side though so don’t be surprised if you’re shoulder to shoulder with the customer next to you."
"It's a bit crowded inside."
"This is the original and is a very small space so you’re touching elbows with other diners - a very casual and quick eat sort of place."
"Food is amazing but the seating area at the bar was too tight."
"Seating is arranged like a bar with just a single long counter and is super cozy with a tasteful wooden decor that fuses traditional and modern vibes."
Value
Pros:
"So cheap - had a starter and two noodle soup bowls with a friend with sake for 20 quid per person."
"Good quality udon at affordable price."
"The portions were generous."
"Very cost-effective!"
"Very comforting food and appropriate portion sizes, not too small or large."
"Fair prices and authentic."
"It's rare you find a place that represents value for money."
Cons:
"Price is not extremely expensive but people might find it overpriced with a regard to its portion."
"Lunch for 2 with 2 drinks, no sides came to around £40. Service charge is 13.5%"
"The portion overall seemed quite small, and the broth itself quite bland."
"very sadly has massively dropped in standard while increasing in price. i ordered a vegetable tempura with udon- udon was undercooked."
"Albeit a bit pricey for udon."
"Only sucks that they charge for an extra bowl of the dipping sauce when they don't give enough."
"12.70 GBP for Buta Miso with nearly nothing inside except udon. 13.5% service charge."
