I've been here 4 times over the past 7 years and the food is consistently of the highest quality - as good as anything I ate when in Japan. The staff always seem rushed, but I've never had problems with waiting for food and have always had a delicious meal. One of my favourite Japanese restaurants in London

While the food is acceptable the service was rude. The waiter insisted that we sat at a particular table the we did not want to and then we did not get the food until we complained

Everyone seemed to enjoy the food and it was good value for what you got. Unfortunately the service was chaotic throughout and it took well over an hour for a main meal to arrive. The manager was not concerned about this and did not even offer an apology. Given the huge choice of other restaurants in the area and in... More

We were in the neighborhood and wanted Japanese food, so this was a great find. 4 stars!! 1st star: Managing customer expectations - We showed up around 9.00p and the restaurant was pretty packed. The host warned us that the kitchen was really busy so there could be a wait. I appreciated that. 2nd star: Extensive menu - I mean,... More

Four work colleagues and I visited Thursday lunchtime, one of my colleagues is Japanese. At my offices we do order now and again the lunch boxes which are delivered for £6 per box. These are great and I was looking towards going to the restaurant. As I work for a Japanese company quite a few people from Japan have these... More

Good meals with lovely service which can be slow but always friendly. Excellent bentos and sushi. Only hitch is that you will come out smelling of food each and every time. Also does not open on weekends.

Went for lunch. The sushi was pretty good (definitely better than supermarket sushi, or Wasabi). There is a huge range of sushi and hot food. It gets very crowded but service was fast, efficient and friendly. I was a bit put off by my pork and prawn dumpling - the meat didn't seem great quality, and was still quite red... More

I work for the company located in the building in which Mugen occupies part of the ground floor. The company is Japanese, and therefore has a large number of Japanese ex-pat staff, who visit Mugen regularly. I tend to go in fairly often too, last time being this week. The restaurant has always (I have been working here 6 years)... More

I went to Mugen with a friend last night. I have been many times before at lunchtime but havent been for about 12 months. We ordered Salmon Teriaki and Chicken Skewers to share followed by a special Ramen. The salmon was solid and rubbery and was not fresh. It appeared to have been re-heated. The chicken skewers were average to... More
