At the Holborn end of the street. Outside, the windows are framed in modern bits of old metal welded together, once useful and now kitsch. As expected, the bar has some good Belgian beers. Make sure you get there early and grab the comfy sofas in the window. Up past the sofas in the windows, through the doors and into the bistro where the decor is imaginative.
Tables are on either side of the wall and at the end is a long bar.
Food is reasonable, leans towards the Belgian but tends towards the tepid. As everywhere, portions of Moules have lessened, though at least you are not served by monks a la Belgo Centrale. Wine tends to be French and can be various, so I would suggest you stay on the cheap side. No, this place does not excite me - it's functional and that's it. You won't see many Belgians there.
