Brussels (Grand Place and the Marolles) ★ 4.5
Brussels is 32 min from Ghent by fast train: moules-friet at Chez Leon near the Grand Place, Sablon waffles and the Marolles flea market lunch stalls.
Tip: Take the 08:00 departure and do the Sablon market first (Saturday and Sunday mornings only); the Grand Place restaurant strip is tourist-heavy after 12:00.
