Fried roti from street carts and mataba (stuffed roti parcels) from Phra Arthit — a legacy of Bangkok's Muslim community.
Thin dough stretched and folded on a hot griddle with egg and condensed milk, or banana — 30–50 THB; the most common sweet street snack.
A stuffed roti parcel filled with spiced minced chicken or beef, egg, and vegetables — a savoury meal in itself; found at specialist shops near Phra Arthit.
Roti arrived in Bangkok with Muslim Malay and Indian traders — the street cart roti is now a Thai institution despite its foreign origins.
Phra Arthit Road (near Khao San area) has the most famous mataba shop; roti carts found near night markets and university areas throughout Bangkok.
Specify sweet (banana, condensed milk) or savoury (mataba with chicken or beef) clearly, since the same cart often makes both — prices are low enough to try one of each.
Evening is when most roti carts are busiest and freshest, coinciding with the broader night market and street food scene coming alive across the city.
