Yes, the place is very small and for first few minutes the smell is awful (especially when guys start frying something).
But the food is fantastic - crabs, oysters, prawns - everything is absolutely fresh and tasty.
Also, I recommend crab on toast - very nice thing.
Oysters - I liked most those from Gallaway.
We visited the Klaw twice - just could not resist the temptation! Though, I should admit that prices are high for street food.
