The Flask pub is a beautiful Victorian treasure that's become a modern example of the traditional London pub. Welcoming a diverse range of customers from post-work drinkers to those dining out, it's the ideal setting for ultimate relaxation and indulgence.

The Flask has a stunning decor that is rich in history, with a typical and well-restored wooden bar and antique pictures, while the conservatory is the perfect sun trap that gives The Flask a bright and airy feel. There are plenty of places to sit, with a choice of bar stools and cosy booths that create a friendly and sociable ambience that The Flask is famous for.

The menus feature British pub classics alongside the very best seasonal produce, and the dishes are prepared with skill and care to make you feel like royalty. On a Sunday, The Flask serve indulgent roasts, with options such as Hertfordshire half chicken, West Country beef rump or parsnip & walnut nut roast as a vegan option. The roasts sit alongside plenty of other mains for those in the mood for something different, as well as an array of decadent starters and desserts.

Nestled in Hampstead, The Flask is just a stone's throw from Hampstead Underground Station and a short walk from Hampstead Heath.

    Came for the Sunday roast and the meal was good but on the expensive side. Gravy was watery and the pork was a little dry. The chicken was flavourful and tender, not dry at all. Lovely stuff and great vibes.

    Perfect Sunday Roast at The Flask Pub - I had a wonderful Sunday roast lunch at The Flask Pub in Hampstead. The roast beef was cooked to perfection, accompanied by all the classic trimmings, and the portion size was just right. We did ask for extra gravy, which was promptly brought to the table, adding to the meal’s enjoyment. For dessert, we shared a delicious rhubarb and apple crumble with vanilla ice cream, which was the perfect end to the meal. The atmosphere was cozy, with pleasant background music that wasn’t too loud, making it easy to chat. A thoroughly satisfying experience and a great spot for a traditional Sunday roast!

    Service was good. We had the special 3 course traditional Christmas lunch with main being turkey, pigs in blankets, leg ham, yorkshire pudding, roast potatoes, brussels sprouts, carrots and parsnips. It was a huge meal. Would have preferred to pay less and have less of the main meal as we had to take half of each main meal home in a takeaway box, but it shows how generous the servings were. Also highly recommend ordering a lemon, lime and bitters drink. 🥤
