We went to Corso's to try the fish fry - we love this season and all the local fish fries. Every year we try a couple of new fish fries. After reading other reviews, we didn't get our hopes up. Well - we were pretty pleased. The restaurant was busy at 6:45 on a Friday night, we were greeted immediately and seated. The waitress, Carole, came to the table to take drink orders. The glasses of wine and glasses of ice water came promptly, along with bread and herb butter. We both ordered the fish fry, with cole slaw or house salad and baked potato / French fries. The Lake Erie perch was hot and delicious, with a seasoned breading (not a tempura breading). The salad and cole slaw were fresh, the French fries were not house cut but were hot and cooked appropriately. Carole was attentive but not intrusive. There were 3 other waitresses, I think, all of them hustling.
We will go back to try some of the Italian items (Carole described their several distinct sauces - tomato, marinara, mushroom, meatball...), as well as take some friends to another Friday fish fry.
This isn't a fancy place, but the staff was friendly and professional and our food was good.
