Given the sky high prices, you wonder why Maru is so crowded on Tuesday and Friday nights. Well, these are the days when the fish gets flown in from the Tsukiji Fish Market in Tokyo, and the faithful join the queue to get their fix of fresh sashimi. Granted, most of the customers at Maru are Japanese businessmen earning Tokyo salaries, but anyone who is willing to part with a bit of cash should come to Maru just to sample fish at its finest. The otoro tuna is the melt in your mouth variety, the freshwater unagi eel is as taste bud tingling as it gets, and they even have puffer fish on the menu, you know, the one that if it is not sliced up perfect by the chef, can end your sushi eating days within seconds. There are other items on the menu, like tasty zarusoba, cold soba noodles dipped in soy sauce and wasabi, but hey, you might as well join the masses and put your credit card on the table and dig into some of Bangkok's best fish, that is what you are here for.
