There is a covered parking lot very close to the venue at 3501 Wazee St. There is also a covered parking garage at The Source, which is about a 10 minute walk. 1st hour is free, then it is $8/hour. There are other parking garages nearby as well. There are a few free parking spots right across from Bigsby's but those are very limited. Carpooling/DDs/Uber-Lyft are encouraged.

There is an indoor area and an outdoor patio if the weather is nice. If the weather does not cooperate, the venue will be all indoors.
