This is basically Wagamama's for Thai food. And I mean that in a bad way. For starters, there are communal benches full of noisy diners, each raising their voices in crescendo in an attempt to be heard. Then, there's the beer which consists of 4 varieties of bland Asian lager - even Waga's stocks Asahi Black. But at least the food is decent, with only the calamari being stand out, but the beef I had was tender, the prawn starter was good, and generally decently edible. There's better Thai in London (Churchill's being the obvious example) but probably not in W1 for the money.
The biggest problem is with their focus being on the fast food, cram-them-in, mentality that pervades the place. For starters, the young upstart waiter will cram you into whatever space he thinks you deserve (probably based on your dress sense, height, religion, colour, or bra size, but who knows how their two brain cells co-operate) and leave you to rot. (Note to staff: don't sit people of my size next to the fat bloke - there won't be room for both of us on your little benches.)
Then, ask to be moved, and one "seating Nazi" will grunt and point you to another table. At which point, another seating Nazi will tell you that you're in the wrong and have to move - followed by a dressing down about not keeping him informed. (Note to staff: communicate amongst yourself before harassing the customers.)
Immediately after being re-seated (for the second time) a waiter arrived for a drinks order. "Give me two minutes, please." Ten minutes later, no one had returned, due to the aforementioned staff member being on a "chat break". Eventually we got a waitress to take our order. A different one brought the drinks. A different one brought the food. And a different one brought the bill. Not an issue in itself, but it makes them all look clueless as there's no shared memory or concern about your dining experience. See above.
So, what should have been a nice quiet post-work meal was a Fawlty Towers-esque display of customer mismanagement.
Food: good. Service: pitiful. Verdict: never again.
p.s. splitting the bill means splitting it into equal portions. There's no need to ask "how much on this?" for each card.
