I was there some time back shortly after it opened. It was v nice but yeah you wouldn't be stuffed by any means. A bit fussy for me but everything was nice. They had no toilet in the place at that time believe it or not. No idea how they were allowed open without one.
Would think they are shrewd lads. It's tiny they can't be paying fuck all rent and the fit out was minimal. They only open 3 evenings a week so are serving max 72 people a week. The only expensive ingredient on that menu was the fish the rest was just well worked veg and herbs. And they are charging well for it. Fuck all waste I'd guess.
