Kem-Kon Khaosan
182 Thanon Tani, Khwaeng Talat Yot, Khet Phra Nakhon, Bangkok 10200
Order the fried oyster mushrooms first, they carry the menu. The khao soi is the second order if there are two of you; the curry spices come through full-strength on the vegan rebuild. Lead with the Thai section rather than the pasta. Solo travellers should grab a bowl of boat noodle soup and a side of the mushrooms.
The room is contemporary and relaxed, the kind of small restaurant that does not announce itself on a Khaosan side street. Plant-based Thai is what Kem-Kon does, and the Khaosan location is one of five across the country.
Fried oyster mushrooms are the dish to start with. Crispy outside, tender inside, and the kitchen has clearly built the recipe to stand on its own rather than imitate something meat-shaped. They appear on every Kem-Kon menu and they hold up here.
The khao soi gets the rich, aromatic curry treatment with vegan chicken pieces in place of the usual. Boat noodle soup carries peppery depth that the original is known for. Teriyaki tofu plays the sweet-umami balance honestly. Vietnamese noodle soup, creamy tom yum, and Thai spicy glass noodle salad fill out the savory side.
Desserts run wider than the standard vegan-cafe drill: strawberry cheese pie, red velvet cake, ice cream. The menu reaches for the same range a non-vegan Thai-fusion place would.
You are in Phra Nakhon at 182 Thanon Tani, a five-minute walk from the Khaosan strip itself but quieter once you turn off. Cash and digital payments both work. If you are vegan and Bangkok is overwhelming you on the food front, this is a 25-minute stop that resets the trip. Bring a friend, share three dishes, and order the strawberry cheese pie for the table.
