I didn't really want to spend a lot of time describing this epic fail of a dinner, hence the brief post above. But I suppose I should at least elaborate a bit.
"Mediocre food" is pretty much exactly what you would expect: chewy tenderloin, whitefish piccata with no lemon flavor, a Thai shrimp appetizer special with no Thai flavors, undercooked vegetables, and food that was mostly just bland and uninteresting.
"Dreadful service" probably makes you think that the service was too slow, but in fact the problem was the opposite. The four of us ordered a couple of sharable appetizers, then a soup/salad course, and entrees. They brought the soup and salads when we were only partway through the appetizers. Then they brought the entrees when we were no more than halfway through the soup and salads. Dreadful, indeed.
Now I'm done.
