Mitchell's is one of those restaurants that I never find to be disappointing but never have a pressing need to come back. Meals are hit or miss, albeit reasonably priced. Waitstaff is typically pretty good. But they just don't have the wow factor.
It's seafood that's better than Red Lobster, but it doesn't have much character. Like most seafood establishments in Pittsburgh, they do have a good Happy Hour but I'm never in the area that time of day.
The cod with lobster Oscar topping is a prime example. The bernaise sauce is not very good, and neither is the potato hash, but he fish itself is cooked well. Decent appetizers and a good wedge salad, so at a future visit I might stick to finger food.
