This is my second trip to db Bistro Moderne. 
I am glad to see that the famous Original DB Burger is available on the Prix Fixe Menu.  The 2 course Prix Fixe Menu costs S$42 + 10% service charge + 7% sales tax.  It includes a soup/ salad and 1 entrée (3 options each).  The 3 course Prix Fixe Menu costs S$52 + 10% service charge + 7% sales tax.  It includes a soup/ salad, 1 entrée and 1 dessert (3 options each).  If you choose the DB Burger as your entrée, it costs an additional S$15.
My first course was the White Asparagus Soup.  Not too bad.  Creamy.
My entrée, the DB Burger, looked small but was very filling. The DB Burger consists of a sirloin patty, filled with braised short ribs and foie gras, served on a parmesan bun.  The foie gras was heaven!  It just melted in my mouth.  Loved, loved, loved it!  The standout of this dish is the fries—-perfectly crisp.  I heard they were fried in pork fat.

Having eaten there for a variety of reasons, it has always been a great experience. Though may be on the high side, not necessarily overpriced.
Service staff has always been efficient, courteous and attentive. (Have read that some diners had different experience when it comes to service).
They will accommodate to requests.

Just had the Original burger today. Beef patty was too dry and salty but the fries were awsome?? Service was very good with great ambience!
