We split 200 grams each of the scallop (Japanese style), beef (Ancient style), and duck (Sunrise style) between 3-4 people and it destroyed us. If you're ordering tartare, you probably don't also need the Tartare Caesar, which comes with a hunky side of tartare of its own.
The three styles we chose were at most very mild. We tried the tartare sampler first, and lots of thought went into the final configuration to make sure the meat would be complimented and not overpowered. I felt pretty good about our decisions.
$5 happy hour cocktails are delightful if you like fruity drinks that are on the sweet side.
