I recently left a review for the excellent, but pricey, upstairs steakhouse.
Now, this downstairs bar... so cool! Other than the overlapping of some cocktails and those chips... oh, those chips (have I mentioned the chips?), the downstairs is completely different than the above restaurant... a bit on the cheaper side, but smaller dishes and still perhaps pricy depending on your take on it... it doesn't help that I have to order about 12 cocktails every time I'm down there, but alas... it is what it is.
It may be worth noting that you can't order the amazing steaks downstairs, the upstairs menu is genuinely upstairs only, so if you need a steak that's where you'll need to book. That said, I've happily eaten downstairs many a time (Kimchi Burger, NOM!) and unless I need to have a steak I actually prefer the downstairs since it's a more relaxed atmosphere... the food is still quite good without being anything near typical bar fare, truth be told I'm craving it now actually!
Along with the Shaky Pete's, mentioned in my upstairs review, they do some spectacular bowls... they're meant to be shared, but you can manage one solo if you're up for it... the good news is that these are actually nice, and nice looking, bowls of drink... not your typical bowl or pitcher affair. (Small red berries and floating half cut fruit adorned with burning sugar, as in on fire, make it into one of my favourites... sadly I can't describe the fruit better than that, I'm not a grocer, but it looks awesome and certainly not frozen fruit thrown into a cocktail pitcher.)
They also do an amazing Nuclear Banana Daiquiri, assuming bananas don't gross you out... it's especially fun for milk allergists as it tastes so rich and creamy, but is actually milk free... it's a dessert and a drink in one, without the lactose punch that most dessert drinks carry.
The drink prices can be a bit high, but not if you're used to drinking creative cocktails in this area... £10 is the norm so I can't really dock it for that, and at least their drinks are tasty and creative.
The downstairs also has a fascinating architecture and look to it... sadly I can't remember the story behind it, the bowl drink took that memory from me, but it was something like a brothel, strip joint, etc., and once you're told the story you can picture it... one of the coolest looking bars I've been to, and a joy to know it's quirky look is mostly original... think old mirrors everywhere, jade green tiles, gold trim, and a few booths set into the walls of a dimly lit basement and you'll get the idea. (Although I'm not doing it justice with that description.)
The at seat service is just what you would want, a middle ground between personal and attentive.
As with the upstairs booking is recommended for the downstairs bar, but perhaps not as essential... it's pretty small however, so it's worth checking before heading out. read more
