We will meet either at your preferable location or at the first bar, it's totally up to you.
The very first place will surprise you with its uniqueness and style. It will have few bars and restaurants under the same roof so you will be able to get a dinner there as well. It has live music and extremely cool vibes.
The second place is a rooftop with good cocktails(all places serve amazing drinks btw) and the third one is a hidden bar in a artistic/lively neighborhood and considered to be one of the coolest places in London among local people.
I won't disclose the names, of course. But I can assure you you're pleasantly surprised. We can also adjust some places to your needs.
