Tigge, it is difficult to guess how any particular night is going to be crowd-wise. Saturday nights are the busiest year-round and thus always a lot of fun. Friday nights are definitely very iffy. During summers and other tourist seasons (like Spring Break & over the holidays, it can be packed too. At other times it will be less crowded and sometimes rather empty with the bartenders standing around waiting on customers. However, if there is a big convention in town then it can be crowded any night! If you can switch your visit to a Saturday night instead of Friday night you'd be sure to have more partiers out there with you.
Missec, you're welcome.
