That parking lot has been gone for a long time, Bull. I think you're referring to the lot between 9th & 10th, P & Q. That's where the Embassy Suites sits today, but about a decade or so ago that was a REALLY happening place.
I cannot pimp Lazlo's enough to everyone. It's a VERY good pub, they have some of the best microbrew you'll find anywhere, and their lounge is roomy and has several TVs.
The Haymarket area (where Lazlo's sits) is about three/four blocks from the stadium, close enough that you can stand outside and hear the crowd roar. There are several pubs/eateries there, and I recommend all of them depending on your taste.
There's the Misty's in Havelock which is the Grand Old Spot to go before a game, but Misty's has also taken over the old Crane River at 11th and P, so there's a downtown Misty's, too. I always go to the Havelock location, so I don't know anything about downtown Misty's, but I assume it's very good, too.
West and north of the stadium there are several lots where the tailgates set up. I usually go to the lot underneath the 10th Street overpass since I have friends who hang out there.
