First Ward Park has a great event each Friday over the summer where they host live music, food trucks, and beer. You get a gorgeous view of the skyline and a great relaxing evening! Bring a blanket or some lawn chairs, dogs and kids are welcome, and they have an area roped off where you can drink alcohol.. but I think they prefer you purchase from the vendor, not bring your own. The park is also just across the street from the 7th Street Market, so if the food trucks don't strike your fancy, you've got a lot of great options close by. Additionally, the park also has it's own restrooms that were surprisingly clean for a park bathroom and very convenient.
Parking around here is actually pretty good for being uptown. There is a ton of metered street parking right around, but on Fridays after 6, that should be free. The 7th street garage is also close and is usually only $5 for after 6pm.
