We were in Vegas this past weekend and wanted to watch the game at a Bear friendly bar. One of the dealers directed us to a place called La Piazza located at 1000N Main St. near Main and Washington. It's located closer to the downtown area and inside of a Best Western hotel. About 5 - 10 minute drive from the part of the strip where we were staying. The owner was from central IL.
They had a good crowd there and the service was really good. They had the usual beer and bar food (wings were awesome, pizza, etc.) but they had a pretty extensive list of menu items to provide something for everyone. They had some side games going on too like squares, final score, and video poker machines built into the bar.
I would definitely go there again since it was all Bears fans. If you don't want to hang out in the big casino sports books and want a place that feels like a local, neighborhood bar, this is the place.
