Venue for 2-3 hours for ~80-100 person happy hour on a Friday in Jan?

Like it says on the tin; trying to find a location ideally for under 5k for a happy hour / mixer, like 5-8pm on a Friday. Would be great to be on or near the water or a rooftop. Would also consider Miami, but most attendees are staying in hotels and airbnbs near the water without cars. Somewhat flexible on the vibe (dive bars okay but something more mid tier desired), and can BYOB or do open bar. I am actually NOT opposed to Flanigan's if you can let me know the price lol.
