Super cool and unique - this is a one of a kind for sure!
We had a great time in this underground bar. Staff was very friendly and helpful with the extensive drink menu. Great place for date night, drinks and conversation.
I'm sure you know the backstory so I'll just share some hints:
Undertow is located in the basement of Sip (a great place for a beer/bite as well).
No food but, great drinks.
Make reservations!! Walk-ins are welcome but, the wait can be long.
Place is small and cozy - which makes for great conversation..
Visits are capped at 90 minutes - at first was strange but, you quickly realize just how tiny this place is and they need to churn the seats plus, the drinks are great and strong - 90 min is plenty to get your groove on.
I would limit groups to four or less - it's tight!
Overall, a really fun spot to check out!!
