This could/should be in the Ebisu thread but no biggie.
It's a shame that it's perhaps the oysters gave you a stomache-ache, it could have happened anywhere though. There's Advisory's up in every restaurant about the risk of potentially getting a stomache-ache from fresh oysters no matter where you eat it, be it Joe Fortes or Blue Water. Impossible to tell.

Found at BC Health:
"The consumption of raw or undercooked oysters have been the source of sporadic cases and outbreaks of foodborne illness. Bacteria and viruses present in ocean water can accumulate in oysters and cause illness when consumed without adequate cooking, especially in vulnerable people.

Vancouver Coastal Health advises:
“The consumption of RAW oysters poses an increased risk of foodborne illness. A cooking step is needed to eliminate potential bacterial or viral contamination.”

At Ebisu I guarantee that we shuck all oysters only when ordered and we go through hundreds of them daily so it's ALWAYS fresh, no oyster sits in the restaurant for more than 36hours.
I was working on Tuesday, did I seat you? (I'm the only guy in the restaurant) ... that's weird that you didn't have menus. Usually the same person that brings you to the table would already be carrying a hand full of menus to lay on the table.
What dishes did you try? I could have recommended you some of our more popular dishes. Our menu has about 80 items not every dish can be "wow" hehe there are the generic filler dishes that cater to the simple public and the tastier ones.
