Big Al's is fine. It's diner food and you get what you expect. It took us two tries to go here for breakfast on a weekend. The first time was at about 10 a.m., and there was a line out the door, and we didn't want to wait. The second time we got there closer to 9 a.m. and we got a table right away.
I ordered the corned beef hash, which is supposedly the dish to try. It's not terribly memorable, but it was good. The service was adequate and the mood of the place was generally up beat. I left full and satisfied, but not inspired.
While I would go back without any reservations, I wouldn't do so with any great enthusiasm either. Give it a try ... or don't ... you'll be fine either way.
