La Diosa, Buenos Aires
This was my favorite place in BA. You can eat dinner here and enjoy a variety of entertainment such as live music, comedy acts, etc. The tables are eventually cleared into what becomes a large dance floor. The food here is great and the after dinner part never disapoints. Don't get here too early as the after dinner party really doesn't pick up until 1:30 or 2:00 AM, so if you plan on having dinner here and staying after, prepare for a long night. Thursdays through Saturdays are the best days.
Dress Code: Pretty normal. Nothing fancy needed, but may not want to wear sneakers.
