Make sure you don’t walk past the entrance for The Boundary as it is not particularly well signposted (perhaps on purpose!). The Rooftop Bar and Grill is on the sixth floor and is a gorgeous space with fires, large sofas and blankets for when it is colder. You can’t make reservations in advance just for a drink so try your luck on the day and be prepared to queue. We were lucky enough to go straight in – two drinks plus service was around £16.
The views are not as impressive as some other rooftop bars (Queen of Hoxton and Madison for example) but it has a nice atmosphere.
The restaurant (both on the rooftop and downstairs) offers French / Mediterranean cuisine – keep an eye out for special deals. I have seen 3 courses and a glass of champagne for £29 per person, which is good value. The general a la carte menu is fairly pricey.
