"The tonkatsu is savoured with demi-glace sauce. Though the tonkatsu gets top billing as the restaurant’s speciality, the demi-glace, simmered for a full 10 days, surely deserves equal mention. From his mentor, who trained in yoshoku, the second-generation owner-chef inherited not only the flavouring but also the old-school dining-hall feel. With the retro building, plate-glass windows and shop-worn chairs, time seems to have stood still. It’s no surprise that Tonkatsu Ichiban was founded in 1960." - Michelin Inspector
