I finally made it to Grand Concourse at Station Square in Pittsburgh and was pleased overall with the meal. The service wasn't as good as I expected, but not truly lacking either. I'd definitely return and would recommend it without hesitation.
We were going to be seated in the River Room, which does have nice views of the river, but the tables along the window were very cramped and the noise level was quite high so we moved to the main dining room. The River Room tables away from the windows (much quieter) were all filled.
We started with the dynamite scallops (on Aimee's rec) and they were excellent. Individual scallops on the 'Shell Oil' type shell with crab topping. We also had the Charly's Chowder wish was good, but seemed a little bland and not all that hot. We also had 1/2 dozen oysters and here is where the service started to get a bit off. We were mulling over which of the oysters to get (3 or 4 varieties) and the waitress clearly heard our conversation. We finally decided on the east coast oysters. After we'd finished all the appetizers and were into the entrees, I asked the waitress if we could have gotten an oyster sampler, and she said yes. While I should have asked this before ordering, she, again, clearly heard us discussing this and made no suggestion. And while I know I am impatient, it also took quite a while to get the bread basket (with some spicy jalepeno rolls).
We had broiled Mahi Mahi topped with the Oscar topping (jumbo lump crabmeat, asparagus and bearnaise sauce) and the grilled sole with the shrimp brochette accompaniment (5 nice grilled shrimp). The rice, mashed potatoes and vegetables were all good though nothing special. It took longer than I like to get the bill (and it wasn't super crowded), but nothing catastrophic. The waitress was young, though that should not affect the service.
When I return, I'd like to try some of the specialty shrimp dishes, as well as the crab cakes. All the seafood we had was very good quality and I doubt any of the seafood dishes would be a bad choice.
Thanks to Aimee for the dynamite scallops recommendation. Top Notch!
