Sure, bars are great, but sometimes it can be a little dangerous to just sit around and drink. With an open tab, a large selection, and nothing to do but chat with the bartender, watering holes can quickly get expensive. That's why activities at bars are a good choice: They offer things to do so you can set down your glass now and then. The popular Berkeley bar Thalassa offers dozens of pool tables to potentially interfere with overindulgence that may come after a few too many hours sitting and sipping. Dimly lit with an open yet inviting floor plan, Thalassa is a popular spot for college students looking to unwind after a long week in class. The drinks are reasonably priced, and there's also shuffleboard available for those who aren't into billiards. But the best perk? They accept pool table reservations for two or more during weeknights; perfect for when you're planning your day and know for a fact that you want to slam a few balls before the night is through.
