— What this is

A bungalow verandah, transplanted to Cardiff.

Picture the long Indian afternoon: a ceiling fan, marble tables, the kitchen running all day. Cocktails arrive before the food. A bottle of cold lager comes with it. Chai lands at the end. Nobody hurries. That's what we wanted to bring to High Street.

The Lunch Thali · weekdays · 12 – 3
One kari, rice, roti, dal, raita, pickle, poppadum.
£12.90
— The all-day rhythm

The kitchen runs all day because the day does.

Most Indian restaurants in Cardiff don't open till five. We open at twelve. Drop in for chai and a paratha at quarter past eleven. Build a long lunch on a Saturday. Or come at half past nine with a friend and the appetite for one more plate.

Fri / Sat / Sun
10am
Brunch.

The long Indian breakfast. Aloo paratha with butter and pickle. Masala eggs. Bottomless chai if you settle in.

12pm
The Thali.

£12.90 every weekday. One kari from today's board, rice, roti, dal, raita, pickle, poppadum. Forty minutes if you must.

3pm
A long afternoon.

A plate of chaat. A G&T with curry leaf. The Chai Flight on a wooden board. Nobody will hurry you.

7pm
Dinner.

A Maharaja Old Fashioned to start. A lamb shank with parotta. A bottle of red. Pudding if there's room.

10pm
Karak chai.

A small strong cup before you go. Or one more cocktail. Friday and Saturday the kitchen runs to eleven.

The leisurely Indian meal that nobody rushes.

— The whole idea, in one line

Picture an old bungalow somewhere in India. Thirty-five degrees outside. The verandah catches whatever breeze is going. A ceiling fan does its best. Lemon water on the table. A bowl of cashews. Chai arrives without anyone asking.

A bungalow verandah at three in the afternoon — ceiling fan, marble café table, brass kettle, palms in terracotta pots, late-afternoon light through wooden shutters. Chai St Indian Bistro Cardiff.

Someone comes back from the market and the cook sends out something small and hot. By four, the bar opens — a gin and tonic with curry leaf, a cold beer for the man who's just come in from the heat. Mid-afternoon, a plate of fried fish with a lime. By six, onions are frying and people are coming home. Dinner is a curry, rice, dal, another beer. After dinner, chai. Nobody rushes. Nobody is sent away. The kitchen runs all day because the day runs all day.

That's what we wanted to bring to High Street. Not a curry house, not fine dining, not a chain. An Indian bistro — open from twelve, running through till late, the same kitchen and the same bar running through the long afternoon. Cocktails before. A bottle of beer or a glass of wine with the food. Chai after. Thali at lunch. Small plates in between. A proper dinner in the evening. The Chai Flight if that's all you want.

Some of what we cook came from streets — Mumbai's vada pav carts, Kolkata's kathi roll wallahs, Old Delhi's chole bhature counters. Some came from home kitchens — grandma's chicken, dal that cooks for a day, the rogan josh you could only get if you knew someone's mother. Some came from the regional traditions — Rajasthan's laal maas, Tamil Chettinad, Kashmir's rogan josh, Kerala's coastal kitchens. The dishes have lineage. The bistro has time.

A brass thali on a marble café table at Chai St Indian Bistro Cardiff — six small bowls of curry, dal, raita, chutney, pickle and poppadum, beside a half-glass of red wine and a cold Kingfisher beer.

The address came to us with a history we take seriously. Mint & Mustard put 15 High Street on the map — the Michelin Guide's best Indian restaurant in Wales. The kitchen has not forgotten. The same family. The same hands on the pots. A different table.

Same kitchen. New table. Open from twelve, every day.

What we are. What we aren't.

Four short answers, in case anyone's wondering.

01
Not a curry house
An Indian bistro.

A Maharaja Old Fashioned before. A bottle of Kingfisher with the food. Karak chai after. Marble tables, brass fittings, ceiling fan. The food is Indian. The room is its own thing.

02
Not fine dining
A bistro you can rely on.

Walk in. Order what you like. A thali doesn't mean a long evening, and a long evening doesn't mean a tasting menu. Reservations welcome. Not required.

03
Not a chain
One kitchen, one room.

15 High Street, Cardiff. Run by the family who put this address on the map twice over — first as Mint & Mustard, now as Chai St.

04 · The big one
Not just dinner
All day.

Open from twelve, every day. Brunch on Saturdays and Sundays. Thali at lunch. Small plates in the afternoon. Dinner in the evening. Chai whenever you want one. The kitchen runs all day because the day does. Pop in when you like.
