I like to come here when I am craving bibimbap in a traditional setting and I feel like I can splurge money-wise that day. In addition to the bibimbap, I have tried the korean ramyuen, pancakes, bulgogi, and mandu. While all of the food is satisfying, it doesn't seem like a great value due to the lack of ambience and poor service.  However, the food really does hit the spot if you have a Korean food craving.

Seafood was not fresh. Nothing fantastic about their other dishes. Side dishes were disappointing. Service was obviously lacking too.

No repeat visit.

Aesthetics wise, the place seems close to a typical restaurant in Korea given the tatami rooms and screens broadcasting Korean mvs and performances. 

However, service and food wise pales in comparison, not sure if it is due to the recent groupon promotion. Firstly, we had reserved a table for 2, but was given a table which was positioned next to a wall, and had 2 chairs side by side. This is definitely not conducive for any conversation and for a moment we thought we were in a library. We pointed that out to the waitress and had to insist on changing to another table, and she pointed out that all the other tables were reserved. We told her that since she could allocate us this table, she could very well allocate it to someone else, and we would take their table, as we were early and most tables were not occupied. In the end she agreed. Bad planning, and service, as it is the first restaurant I seen where the table was placed against the wall, and 2 chairs placed side-by-side. Korean restaurants are usually with the concept of sharing -_-.

Hygiene wise, the cups were dirty. My companion had to request for a new cup. Food wise, we ordered ginseng chicken soup (samgyetang) and beef bulgogi with rice. The food were served pretty quickly, but the ginseng chicken soup was bland, with little taste of ginseng. I have had cheaper versions with more flavour than this. The beef bulgogi was not cooked well -- the beef had not been marinated well enough and the tase of beef was too strong. 

In conclusion, it is a good place IF you have lots of money to spend, and come in a big group. The service for big groups seemed better, where they could have the tatami rooms, or larger tables with better view. If you are in a small group, and want some truly authentic korean food, there are lots of other better choices next to Manna Restaurant. In fact, we spotted so many bbq and korean family restaurants along Telok Ayer Street, as well as near the Exit A of Tj Pagar Mrt.

Strongly not recommended. We will not come back again.
