Depending on the kind of show you're seeing this can be an awesome venue! Even on the lawn where there is more of a communal atmosphere. I've only ever had good experiences here.
Drinks and food start at $10 for a hot dog and go up from there.
Bathrooms typically overflow so get to it early.
Getting there can be a nightmare with transit and the parking lot tends to be a disaster afterwards if you drive. MY ADVICE: walking is quicker and easier.
