A charming Hampstead pub with a classic British menu, generous portions, and a lively atmosphere—worth it for a hearty meal, but expect premium prices and occasional service hiccups.
The Flask delivers solid neighborhood dining through strong food quality anchored by celebrated Sunday roasts and fish & chips, paired with exceptional setting appeal that captures historic Hampstead charm. However, inconsistent execution and variable service speed during busy periods prevent grade A territory, while premium pricing creates value trade-offs that most diners accept given generous portions and the inviting atmosphere.
One caveat: Pricing is on the higher end for a pub, especially for mains and drinks.
