Flask & Beaker

Had a perfect Saturday lunch here today. Amazing service, food served very quickly, reasonable prices and tasted great. Definitely recommend to anyone thinking of having some food before or after walking round Hampstead Heath!

Great pub with great food. First if you are meeting someone, know that there are two entrances. The one on the left is for the pub, the one on the right is for the restaurant. The food is delicious, decently priced, and served quickly. Definitely a place to pop by if you have the time, but be warned, this place is super popular so always busy.

Very bad and hostile service. I’m not sure why, but we were treated very badly from both of the waitresses who served us (both Italians like us) - since we sat down at the table till we left. The only friendly one, was a girl with long braids who unfortunately only stayed with us to take the payment! I’m sure that if she served us, we would have left with a better feeling about this place. Despite the awful service, the food was good and the pub is really lovely and quiet.

Nice pub with surprisingly high quality food. The service is a bit slow, but the waiting is worth.

Relaxed gastropub hung with old prints and designer wallpaper, plus skylit conservatory and garden.

Stopped of after a walk across Hampstead Heath and had a lovely pint of winter warmer. Nice setting.

Most enjoyable visit.Food was superb.Good selection of beers and wine.Friendly staff. Happy days.!!!

The Sunday roast was once pretty perfect here, but these days it's not quite what it once was. The potato came out cold, and gravy without much flavor, and the roast itself was tough and lacked flavour. Still a lovely place for a pint, even if it's generally booked.

Nice pint sat outside watching the world go by.

Went for a Christmas party. Food was absolutely gorgeous and amazing quality considering the average price. Really outdid themselves, staff very attentive and friendly. We've already discussed booking again for next year!!

I've been visiting the Flask for 47 years. The restaurant area used to be a nice patio to sit out on, and there was an outside toilet down the side from the public bar. I also remember some well known faces seen in the pub, like John Hurt, Ray Davies, Alan Clarke, Kingsley Amies, Tony Booth. But all things must change. There is certainly a wider range of food now (although I fondly remember the armadillo pies and Mickey's freshly baked sausage rolls on a Saturday). I still admire the Victorian screens (chromolithographs) by Jan van Beers and glass panels above each time I go in. Amazing they have survived. I wish I had some photos from the old days...

Went for the Christmas party feast!!! What an absolute bargain and as always the flask performed amazingly and all the food was perfect This place is amazing for roasts and the sausage rolls are a must try

Proper pub with wood panelling, hand pump beers and two sides of the bar with plenty of seating to choose from. It's a Young's Pub with their standard menu.

My favourite pub in the centre of Hampstead - tucked down a narrow street, just around the corner from Hampstead Tube Station.The few seats in the street are great for people watching while having a drink. Plenty of seating options inside - my preference being the raised tables by the main entrance.Great food - much better than typical “pub grub” and friendly staff. Definitely worth a visit.

Lovely location, good atmosphere and very tasty food. We had a lovely lunch and I would highly recommend. Best of all it's dog friendly. There are tables outside too.
