The Verdict
The Grammar Room is the all-day cafe that the Olive Group — the hospitality company built by restaurateur AD Singh — opened at One Style Mile in Mehrauli, in a glasshouse beside its older sibling Olive Bar & Kitchen, looking out over south Delhi’s forest ridge. The name plays on a shared love of grammar, coffee and food, and the kitchen serves a Continental, café-style menu prepared to order.
It has the awards to back the room. It was named Bistro of the Year at the 2022 Delhiites Food & Nightlife Awards and won a Best Café (Standalone) honour at the Travel & Leisure Delicious Dining Awards in 2024. On the plate, the dishes people order by name are the TGR fries and the Keep Calm Curry On, and a meal for two lands at roughly 2,500 rupees, with a pint of beer around 350.
The draw is the glasshouse itself, which shifts from a bright daytime room to a softer evening one. Food is dependable rather than ambitious, and orders are made fresh, so a wait of around twenty minutes is normal. As a Mehrauli daytime address with a view, it earns its place; as serious dining, it sits a notch below the group’s flagship next door.
What to Order
The two dishes the cafe is known for are the TGR fries and the Keep Calm Curry On, both menu fixtures worth leading with. The rest of the menu runs a Continental, café line — salads, all-day breakfasts, light mains and desserts — with the coffee program a genuine reason to sit. A meal for two runs about 2,500 rupees, and a pint of beer is around 350; everything is made to order, so expect a short wait.
The Room
The Grammar Room sits at One Style Mile on Kalka Das Marg in Mehrauli, beside Olive Bar & Kitchen and overlooking the wooded Delhi ridge. The glasshouse is the point: bright and plant-filled by day, warmer and more intimate after dark. It opens late morning to midnight and is closed on Tuesdays. The Mehrauli setting, near the Qutub Minar, makes it a relaxed daytime stop rather than a city-centre table.
Why It Works for a Relaxed Day Out
The glasshouse over the ridge makes The Grammar Room an easy daytime choice: a low-key first date over coffee, a solo seat with a laptop, a flat white and the TGR fries, or an unhurried all-day table with friends. The Olive Group polish and the award-winning room give it more occasion than a standard café without tipping into formal dining.
Not For
It is not a fine-dining destination or a quick, central pit-stop — it is a Mehrauli café where food is made to order and a twenty-minute wait is normal. For the Olive Group’s more ambitious cooking, the original Olive Bar & Kitchen next door is the table to book, and anyone after Delhi’s top modern-Indian rooms should look to Indian Accent instead.
Reservations
Reservations are recommended, especially for an evening table in the glasshouse or a weekend brunch, and can be made through the restaurant or the usual booking platforms. Note it is closed on Tuesdays and runs from late morning to midnight; a daytime visit catches the room at its brightest, with the ridge view through the glass.
