I went to Gatsby's while stuck staying at the nearby Wingate by Wyndham (kicking myself for that after finding out there was an HGI across the way).
Gatsby's was a pretty run of the mill bar with food. If you're stuck at one of the hotels near this place without a car (like us) - it is really your only option for a meal late in the evening and it is fine.
The nachos were great and service was fine. Most of the other dishes were a little underwhelming. Â They have some good beers so that was a nice surprise. Â Service was fine.
If I lived in Indy, I would make no effort to go back - but if you have limited options and are looking for a meal or a sports bar it seems like a fine option. It became surprisingly busy later in the night, so maybe it's a good local bar.
